We travelled for 6 months and didn't find any cheaper price for such a room. But most of all, we met there a fantastic guide who brought us during a day across surrounding villages in the countryside. On top of being friendly, he taught us how to cook in the jungle with bamboos and told us a lot about the local culture. It's a really good souvenir. So if by any chance you decide to stay in Chat guest house, don't forget to ask for Fido, the best guide ever.
