Interchange 21

Khlong Toei Nuea

This subdistrict is one of Bangkok's most connected mixed-use zones. Office towers and hotels line Asok and Sukhumvit, while residential sois contain condos, schools, clinics, restaurants and quieter pockets. Asok BTS and Sukhumvit MRT form the main interchange, with Nana BTS to the west and canal boats on the Phetchaburi side. Traffic is intense, so a genuinely walkable route to rail is a major advantage. Supply ranges from compact investment condos to large older apartments. Check nightlife noise, construction, one-way access and whether the route to transit is comfortable at different times of day.
