So, the bad first, it's located near one of the noisiest places in Bangkok by night, and is not super soundproof towards the streets, but if you can live with this, then it's got a super location with minor shops, bars and restuarants right outside, and the NTS is located 200 meters down the street.
The hotel itself is clean, with great facilities, and a lovely staff, though they might chuckle a bit when you order sandwiches for dinner 5 days in a row (I really love my sandwiches) 😃
