Thonglor 21 by Bliston

Khlong Tan Nuea

This is the residential and lifestyle heart of upper Sukhumvit. Main roads are intensely commercial, while the branching sois contain a dense mix of condominiums, houses, clinics, schools, restaurants and neighborhood retail. Thong Lo and Ekkamai BTS stations serve the Sukhumvit side, while canal boats serve New Phetchaburi Road. Deep sois can make first-mile travel slow, so walking distance or reliable motorcycle-taxi access is important. Options range from older family-sized apartments to new luxury towers and rare houses. Compare the specific soi, school traffic, late-night noise and distance to both rail and daily amenities.
