Chanthaboon Riverside Community is about three hours from Bangkok. There are regular air-conditioned buses from Ekkamai and Mo Chit bus terminals.
For a real taste of history, stay at Baan Luangn Rajamaitri Historic Inn (from 1,550 baht a night). This 150-year old heritage home of Luang Rajamaitri. It has only 10 rooms and is in high demand. A few steps away is Tamajun (from 1,500 baht), a lovely boutique hotel by the river. Unfortunately, none of its lovely rooms have windows.
