The Treehouse is one of the best and most unique places to stay in Pai. The property is very large and runs along the Pai river. The landscaping is beatutifully done and is meticulously maintained. The room was pretty cool, completely built out of wood and in a tree. They even had those human nests things hanging from the trees! Elephants from a nearby camp walk through the resort a couple times a day. Really cool.
The restaurant in the resort was cheap and very delicious. We ate there 3-5 times.
The room was comfortable. Came equipt with a medium sized fridge, a/c, and old tube TV. The bathroom was large. Only weird thing to me was is had a shower/tub combo, but no shower curtain. Other than that, great room.
