OK, this is not a five star, but I slept very well, I felt safe, the hotel is away from traffic noise, it has got free wifi, good breakfast (although no fresh fruit but you can ask for them).
I'll be honest, I befriended some of the staff and ended up having diner with them, they were really friendly and nice.
But the hotel has shortcomings : it's new and lacks decorations, shower curtains, foreign TV channels, the wifi doesn't reach all rooms well (ask for rooms with wifi when you book) ... but these are minor details. Overall it's a really cool place to stay for one night in between two flights at BKK.
It's a family owned hotel, not a big international chain. But the 30-something employees there are doing their best to reach international hosteling standards, and they deserve your trust.
