In this building · Keyne By Sansiri
Keyne By Sansiri is a condominium project, developed by Sansiri, located at 766 Sukhumvit Road, Khlong Toei, Khlong Toei, Bangkok. Construction of Keyne By Sansiri was completed in 2013. The development comprises 1 building(s), with 28 floors and 216 units.
Keyne by Sansiri is a 28-storey, boutique Sansiri tower barely 200 metres from BTS Thong Lo on Sukhumvit Road — among the most walkable addresses in the district. Its step-to-the-station position, blue-chip developer and tightly held unit count keep void periods short and command premium pricing, supporting a firm gross yield in the Thonglor submarket.
Area gross yield: ≈4.5–5.5% · Resale price/sqm: ฿190,000–฿240,000 (indicative — confirm current figures before you buy)
Thonglor is Bangkok's trend-setting lifestyle district — a dense run of rooftop bars, design-led dining and boutique fitness along Sukhumvit 55. Keyne sits on Sukhumvit at the mouth of Thonglor, metres from BTS Thong Lo, so residents reach the action on foot.

Compare with The Crest Sukhumvit 34What residents praise: The fundamentals are strong and reviewers agree on them: the BTS Thong Lo staircase is essentially at the door, the building is clean and well run with three lifts, and the doormen and security team draw warm, specific mentions. The infinity pool on the 7th floor and the gym are both described as clean and — worth noting at this end of Sukhumvit — rarely busy, so the facilities are usable rather than merely present.
Common complaints: The gripes here are operational rather than structural, but they recur across separate residents. The most consequential is sound: the building fronts directly onto Sukhumvit Road, and a resident reports the window glazing does not seal the traffic noise out — on this plot that is the trade you are making. Beyond that, the gym faces south and gets hot even with the air-conditioning running, there is no wi-fi in the pool or fitness areas and the lobby co-working wi-fi is slow, and the pool water runs cold. One-bedrooms are small — 'livable' rather than generous, in one resident's phrasing. An older account complains of an unhelpful juristic office and lift air-conditioning that did not work; both are dated enough to be worth checking rather than assuming.
