Thonglor Soi 4 — Quiet Soi, Quattro Condo and Marché
By Joe Thonglor — Thonglor neighborhood writer & fact-checker · · Last updated:
Thonglor Soi 4 draws around 1,900 searches a month, but search it and you mostly get condo listings — because Soi 4 is really a quiet residential and services soi, not a restaurant or nightlife strip like its neighbours.
This page covers what’s actually on Soi 4, checked one by one on Google Maps on 18 July 2026 — the condo, clinics, boutiques, and the venues that are permanently closed but still showing in search. Every venue, rating and opening time here was checked against Google Business one place at a time, not pulled from a stale dataset (how we research).
Where Thonglor Soi 4 is — and which district it’s actually in
The soi pin on Google Maps says Khlong Tan Nuea, Watthana, Bangkok 10110.
Worth flagging because venue addresses on the soi disagree:
| What confuses people | What some sources say | Current Google Maps |
|---|---|---|
| Subdistrict | The Quattro condo lists “Khlong Toei Nuea” | The soi pin says “Khlong Tan Nuea, Watthana 10110” |
| Which soi Marché is on | Its main address lists “150 Thonglor Rd” (main road) | Building C (clinics) uses a “Thonglor Soi 4” address |
Soi 4 runs off Thonglor Road (Sukhumvit 55) on the even-numbered side, near the Sukhumvit end. For paperwork, go with the soi pin: Khlong Tan Nuea, Watthana.
Getting to Thonglor Soi 4
| From | How | Notes |
|---|---|---|
| BTS Thonglor | Exit 3, walk into Thonglor Road; Soi 4 is near the start on the right (even side) | Walkable — Marché at the mouth is the landmark |
| Car / taxi | Ask for “Marché Thonglor” or “Quattro Sansiri” | Most drivers know Marché |
| Red songthaew | Runs the length of Thonglor Road; get off at the Soi 4 mouth | Cheaper than a motorbike taxi but you wait |
