GM Service Apartment
47 Sukhumvit 20 Alley, Khlong Toei, Bangkok 10110
The shuttle service to Asoke and Phrom Phong is the quiet advantage here. Most buildings this far down Soi 20 leave you walking in heat or waiting for taxis. If you need space and multiple bedrooms without sacrificing midtown access, this is one of the few towers on the east Sukhumvit corridor that scales up to five bedrooms under one roof.
GM Service Apartment sits seven minutes' walk from the mouth of Sukhumvit 20, far enough off Sukhumvit Road that the soi stays residential and quiet. The building dates to 2012 and spreads 89 units across 27 floors.
Room sizes start at 45 square metres for a one-bedroom and climb to a 435-square-metre five-bedroom duplex on the upper floors. Two-bedroom units run between 95 and 111 square metres, three-bedrooms span 182 to 278. Every unit arrives with a full kitchen, in-unit laundry, and furnishings already in place. The layouts favor families and longer stays over hotel-style turnover.
Facilities occupy multiple floors. A swimming pool, jacuzzi, sauna, and steam room share the upper-level deck. The gym runs separate from the pool zone, and the building added a yoga room and dance studio on lower floors. A squash court and kids' room fill out the recreational tier. The front desk operates around the clock, and a shuttle van runs scheduled loops to BTS Asoke and BTS Phrom Phong during morning and evening windows, cutting the walk-and-wait sequence that defines most buildings this deep into the soi.
Rental rates begin at 50,000 baht monthly for a one-bedroom, 80,000 for a two-bedroom, and 140,000 for a three-bedroom. The building quotes a two-month security deposit and charges electricity separately at seven baht per unit. Housekeeping is available on request for 1,000 baht per session. Check-in starts at 14:00, later than many competitors, so plan your arrival if you're moving in mid-morning.
The location works for international schools, EmQuartier, and the Sukhumvit MRT interchange, all reachable without highway transfers. The soi itself is low-rise and residential, lined with older shophouse food and a few local clinics. You're choosing internal space and scheduled transport over the immediacy of being on top of a BTS platform.
