Mumbai's Blue Line (Metro Line 1, Versova to Ghatkopar, 12 stations, operational since June 2014) and Aqua Line (Metro Line 3, Cuffe Parade to Aarey Colony, 27 stations, fully operational since October 2025) together form the most commercially significant metro corridor combination in the city. The Blue Line is Mumbai's original east-west connector it cut the Versova to Ghatkopar road journey from 90 minutes to 21 minutes and remains the eighth most densely used metro line in the world. The Aqua Line is Mumbai's first fully underground metro, connecting South Mumbai's financial districts to the airport zone and SEEPZ in a single underground journey. BedR lists verified, zero-brokerage PGs across all priority zones along both lines from Rs 9,000 per month.

Written by the BedR Editorial Team, Mumbai Rental Specialists. This guide is built on BedR's active verified listing database across the Blue Line and Aqua Line corridors, cross-referenced against MOOPL and MMRC operational data, live PG rent benchmarks from 99acres, SquareYards, and NoBroker (April to May 2026), and on-ground commute times verified by the BedR editorial team. Operational status is confirmed for both lines as of the publication date of this article.

Why These Two Lines Together : The Intersection Advantage

The Blue Line and Aqua Line cross at one of the most strategically important interchange nodes in Mumbai's metro grid: Marol Naka Station. At this station, a commuter can transfer between the elevated Blue Line and the underground Aqua Line without exiting the station complex. This makes Marol Naka the single most connected node between east-west and north-south underground metro access in Mumbai.

For PG seekers, this interchange changes the calculus on two zones that have historically been overlooked. Asalpha and Jagruti Nagar on the Blue Line the two stations between Sakinaka and Ghatkopar that most commuters pass through without considering for accommodation now sit one station from a direct Aqua Line connection to BKC, Dadar, and South Mumbai. Versova on the western end of the Blue Line, once considered remote from the eastern employment corridor, now has a 21-minute metro ride to Ghatkopar and from Ghatkopar direct Central Railway access south.

The combined corridor logic: Blue Line handles east-west. Aqua Line handles north-south underground. Together they create a cross-shaped metro grid that makes localities near either line significantly more connected than their rents reflect.

Priority PG Zones: Blue Line

Asalpha and Jagruti Nagar - The Two Stations Nobody Has Considered

Asalpha and Jagruti Nagar are the two stations between Sakinaka and Ghatkopar on the Blue Line's eastern end. They sit inside a dense residential zone that has a well-developed PG market priced below Ghatkopar East because it lacks the Ghatkopar railway station address. With the Blue Line, that distinction has collapsed. Asalpha is two stations from Ghatkopar and three stations from Marol Naka giving direct Aqua Line access to BKC, SEEPZ, and South Mumbai from what is currently one of Mumbai's most underpriced metro-adjacent residential zones.

From Asalpha and Jagruti Nagar:
Ghatkopar (Blue Line, 1 to 2 stations): 3 to 6 minutes
Marol Naka Aqua Line interchange (Blue Line, 2 to 3 stations): 6 to 10 minutes
Andheri (Blue Line, 5 to 6 stations): 14 to 18 minutes
SEEPZ (Blue to Marol Naka, then Aqua Line north): under 25 minutes

Room Type	Asalpha / Jagruti Nagar	Ghatkopar East	Monthly Saving	Annual Saving
Triple Sharing	Rs 8,000 to Rs 10,500	Rs 10,000 to Rs 13,000	Rs 2,000 to Rs 2,500	Rs 24,000 to Rs 30,000
Twin Sharing	Rs 10,000 to Rs 13,500	Rs 12,000 to Rs 17,000	Rs 2,000 to Rs 3,500	Rs 24,000 to Rs 42,000
Single Room	Rs 15,000 to Rs 20,000	Rs 18,000 to Rs 25,000	Rs 3,000 to Rs 5,000	Rs 36,000 to Rs 60,000

Source: BedR verified listings and 99acres active listings, Asalpha, Jagruti Nagar, and Ghatkopar East, April 2026.

Who should look here: Professionals at SEEPZ, Marol IT Park, or Ghatkopar-adjacent employers. Anyone who needs fast Central Railway access without paying Ghatkopar railway-station-facing rents. Students from VJTI and other central-east corridor colleges.

Versova and DN Nagar: West Mumbai's Most Overlooked Blue Line Zones

Versova is the western terminus of the Blue Line. Most PG seekers heading to Andheri or east Mumbai do not look this far west — and that is the opportunity. Versova is 3 stations from Andheri and 11 stops from Ghatkopar 9 to 12 minutes to Andheri, 21 minutes to Ghatkopar. The locality has a large residential population, proximity to the beach, and a creative-industry profile with several production houses and media studios clustering in Versova and the adjacent Four Bungalows area.

DN Nagar, the second station east from Versova, is the interchange with Line 2A (Yellow Line), giving it connectivity in three directions simultaneously east via Blue Line to Ghatkopar, north via Line 2A to Dahisar, and south via Line 2A toward Andheri West.

From Versova (Blue Line):
Andheri: 3 stations, 9 to 12 minutes
Ghatkopar: 11 stops, 21 minutes
Marol Naka Aqua Line interchange: 8 stations, 22 to 25 minutes

From DN Nagar (Blue Line + Line 2A interchange):
Andheri: 2 stations on Blue Line, 6 to 8 minutes
Malad West via Line 2A: 3 stations, 8 to 10 minutes
Dahisar East via Line 2A: 10 stations, 27 to 32 minutes

Room Type	Versova	Andheri West	Monthly Saving	Annual Saving
Triple Sharing	Rs 9,000 to Rs 12,000	Rs 12,000 to Rs 16,000	Rs 3,000 to Rs 4,000	Rs 36,000 to Rs 48,000
Twin Sharing	Rs 11,000 to Rs 16,000	Rs 14,000 to Rs 22,000	Rs 3,000 to Rs 6,000	Rs 36,000 to Rs 72,000
Single Room	Rs 17,000 to Rs 26,000	Rs 22,000 to Rs 35,000	Rs 5,000 to Rs 9,000	Rs 60,000 to Rs 1.08L

Who should look here: Media, production, and creative-industry professionals working in Andheri West. Students from SVKM's NMIMS accessible from Versova in under 20 minutes. Anyone who values proximity to the coast and a quieter residential character at lower rents than central Andheri West pockets.

Chakala (JB Nagar) and Airport Road: The Employment Zone Stations

Chakala and Airport Road stations sit inside Andheri East's primary employment corridor JB Nagar, MIDC, and the road leading to CSIA Terminal 1. These are not arbitrage zones in the way Asalpha or Versova are. They are the most direct-access Blue Line stations for SEEPZ and airport-adjacent employers, with verified zero-brokerage listings on BedR starting meaningfully below the JB Nagar main-road pricing that dominates aggregator search results.

From Chakala JB Nagar (Blue Line):
SEEPZ: 10 to 15 minutes by auto
Airport Road (next station, Blue Line): 3 minutes
Marol Naka Aqua Line interchange: 2 stations, 5 to 7 minutes
Andheri: 2 stations west, 6 to 8 minutes

Room Type	Chakala / JB Nagar	Marol / SEEPZ-Facing	Monthly Saving	Annual Saving
Twin Sharing	Rs 11,000 to Rs 15,000	Rs 13,000 to Rs 18,000	Rs 2,000 to Rs 3,000	Rs 24,000 to Rs 36,000
Single Room	Rs 17,000 to Rs 24,000	Rs 20,000 to Rs 28,000	Rs 3,000 to Rs 4,000	Rs 36,000 to Rs 48,000

Who should look here: Airport ground staff and airline crew. SEEPZ and MIDC professionals. JB Nagar corridor office workers. This zone also has the highest inventory of short-term verified PG options on BedR for professionals on project-based contracts.

Priority PG Zones: Aqua Line

Dharavi - One Stop from BKC, Still the Most Underpriced Station on the Line

Dharavi Station on the Aqua Line sits one stop south of BKC Station. In-metro travel time: 3 to 5 minutes. This is the most extreme rent-to-commute arbitrage on any operational Mumbai metro line. A verified twin-sharing PG near Dharavi Metro Station costs Rs 9,000 to Rs 13,000 per month. A twin-sharing PG in BKC or Bandra East costs Rs 16,000 to Rs 25,000 per month. The commute time difference is under 10 minutes door to door.

The honest caveat: Dharavi is undergoing the world's largest ongoing residential redevelopment project. Building quality varies significantly by street and society. BedR's on-ground verification is non-negotiable here. Every Dharavi listing on BedR has a confirmed building society name, floor, CHS registration, and verified walk time to the Dharavi Metro Station exit. Do not book a Dharavi PG from any listing source that cannot provide a CHS registration number.

From Dharavi Metro Station (Aqua Line):
BKC: 1 station, 3 to 5 minutes
Dadar: 2 stations south, 6 to 9 minutes
SEEPZ via Marol Naka interchange: 25 to 30 minutes
Churchgate: 8 stations south, 20 to 25 minutes

Room Type	Dharavi	Bandra East (BKC-adjacent)	Monthly Saving	Annual Saving
Triple Sharing	Rs 7,000 to Rs 10,000	Rs 14,000 to Rs 18,000	Rs 7,000 to Rs 8,000	Rs 84,000 to Rs 96,000
Twin Sharing	Rs 9,000 to Rs 13,000	Rs 16,000 to Rs 25,000	Rs 7,000 to Rs 12,000	Rs 84,000 to Rs 1.44L
Single Room	Rs 14,000 to Rs 20,000	Rs 28,000 to Rs 45,000	Rs 14,000 to Rs 25,000	Rs 1.68L to Rs 3.00L

Source: BedR verified listings and 99acres active listings, Dharavi and Bandra East, May 2026.

Who should look here: BKC-based professionals on any budget who want to maximise monthly savings. Dadar-corridor workers in Parel, Sewri, and Lower Parel. Anyone working at CSMT or South Mumbai offices who previously ruled out a central base due to rent.

Prabhadevi (Siddhivinayak Station): Central Mumbai at Non-Central Mumbai Prices

Siddhivinayak Station serves Prabhadevi, one of the most centrally located residential zones in Mumbai. Before the Aqua Line, getting from Prabhadevi to BKC required road travel through some of Mumbai's most congested junctions. The Aqua Line ended that. Prabhadevi to BKC is now 3 stations and 10 to 14 minutes underground.

Prabhadevi has a well-established ladies PG market. Women-only verified PGs in gated society buildings are in stronger supply here than in Dharavi or Dadar West, and at comparable or marginally higher rents. For women professionals targeting BKC or Lower Parel employers, Prabhadevi via Siddhivinayak Station is the highest-value verified PG zone on the entire Aqua Line.

From Siddhivinayak Station (Aqua Line):
BKC: 3 stations, 10 to 14 minutes
Dadar: 2 stations north, 5 to 7 minutes
Lower Parel by road from Prabhadevi: 10 to 15 minutes by auto
Churchgate: 5 stations south, 14 to 18 minutes
SEEPZ via Marol Naka: 10 stations north, 28 to 34 minutes

Room Type	Prabhadevi	Worli Premium	Monthly Saving	Annual Saving
Triple Sharing	Rs 9,000 to Rs 12,000	Rs 13,000 to Rs 18,000	Rs 4,000 to Rs 6,000	Rs 48,000 to Rs 72,000
Twin Sharing	Rs 10,000 to Rs 18,000	Rs 13,000 to Rs 25,000	Rs 3,000 to Rs 7,000	Rs 36,000 to Rs 84,000
Single Room	Rs 15,000 to Rs 30,000	Rs 28,000 to Rs 65,000	Rs 13,000 to Rs 35,000	Rs 1.56L to Rs 4.20L

Who should look here: Women professionals targeting BKC, Lower Parel, or Peninsula Business Park employers. Anyone working in South Mumbai's financial district who previously commuted from Andheri or Goregaon. Media and entertainment professionals whose offices cluster in the Worli and Lower Parel corridor.

Marol Naka: Where the Blue Line and Aqua Line Meet

Marol Naka is the confirmed interchange between the elevated Blue Line and the underground Aqua Line. A commuter here steps off the Blue Line platform and descends to the Aqua Line platform within the same station complex no exit to street level required. No other interchange in Mumbai's current metro grid offers this level of seamless east-west and north-south connectivity in a single transfer.

From a PG near Marol Naka, a tenant can reach Andheri East (Blue Line, 2 stations west), Ghatkopar (Blue Line, 4 stations east), BKC (Aqua Line, 7 stations south), SEEPZ (Aqua Line, 2 stations north), and Dadar (Aqua Line, 9 stations south) all without a surface road journey during peak hours.

From Marol Naka Station:
Andheri via Blue Line: 2 stations, 6 to 8 minutes
Ghatkopar via Blue Line: 4 stations, 12 to 15 minutes
BKC via Aqua Line south: 7 stations, 18 to 22 minutes
SEEPZ via Aqua Line north: 2 stations, 5 to 7 minutes
Dadar via Aqua Line south: 9 stations, 24 to 28 minutes

Room Type	Marol Naka	Central Andheri East	Monthly Saving	Annual Saving
Twin Sharing	Rs 11,000 to Rs 15,000	Rs 12,000 to Rs 18,000	Rs 1,000 to Rs 3,000	Rs 12,000 to Rs 36,000
Single Room	Rs 16,000 to Rs 22,000	Rs 20,000 to Rs 28,000	Rs 4,000 to Rs 6,000	Rs 48,000 to Rs 72,000

Honest Limitations: What These Lines Do Not Fix

Last-mile from Aqua Line station exits varies significantly. The Aqua Line is fully underground and exits open onto street level, not always into pedestrian-friendly zones. Dharavi's station exit opens onto a busy arterial road and the walk to residential PG pockets can add 10 to 20 minutes depending on the specific building. Always confirm walk time from the exact exit gate on BedR listing cards, not from the station pin on Google Maps.

The Aqua Line has no parking at stations. The line runs underground with no bike or car parking facilities at any station. If you own a vehicle and plan to use it for work, factor in the absence of metro-adjacent parking before choosing an Aqua Line PG zone.

The Blue Line frequency drops sharply off-peak. It runs every 3.5 to 5 minutes at peak hours and every 10 to 15 minutes at off-peak. The last service departs each terminus around 11:00 PM. Late-night shift workers should verify the last train timing from their target station before committing.

Dharavi PG verification is non-negotiable. The rent arbitrage is real. The building quality variation is equally real. Do not book a Dharavi PG from any source that does not provide a confirmed CHS registration number, building name, and on-ground verified walk time to the station exit. On BedR, these are standard fields on every Dharavi listing card.

Versova last-mile depends on the sub-pocket. Versova's residential area spreads across several distinct sub-pockets — Versova Village, Four Bungalows, and the beach-adjacent streets at varying walk distances from the station. A PG that says "near Versova Metro" could be 5 minutes or 18 minutes from the exit depending on the specific address. Use BedR's walk-time filter before shortlisting.

How to Use This Guide to Search on BedR

Start at your employment destination, not the PG. For BKC, Dadar, and South Mumbai employers, start at BKC Station on the Aqua Line and move outward. Each station further from your office typically reduces rent by Rs 1,500 to Rs 3,000 per month. The sharpest rent drop on the Aqua Line is between BKC and Dharavi one station, Rs 7,000 per month in median twin-sharing savings.

For SEEPZ, Marol, and Andheri East employers, start at Marol Naka or MIDC Andheri on the Aqua Line. Moving east on the Blue Line from Marol Naka toward Asalpha and Ghatkopar saves Rs 2,000 to Rs 3,500 per month per station step.

Filter by locality name and walk time on BedR. Aqua Line zones require a strict under-12-minute walk filter because of the exit-to-street complexity at underground stations. Blue Line zones can extend to 15 minutes given the elevated station design with more predictable exit points.

Verify deposit and agreement before visiting. BedR shows the deposit amount upfront on every listing card. The Maharashtra Rent Control Act caps all residential deposits at two months' rent applicable to every zone in this guide. Confirm the Leave and Licence Agreement template is available before scheduling a visit.
