I stayed here for a week in November 2017 while in business in Bangkok.
This is a superb choice if you want to be in a calm place while staying for a week or two in Bangkok. Kang, the owner, and his wife, are amazingly nice and the view is pretty. The building facilities are pretty, especially the pool and the gym.
Much better than any hotel you could book. And cheaper too.
A bit outside of the city center but this is perfect if you wish more calm, less pollution and a more local experience. Easy to reach with cheap taxi (3$) and Metro.
