Pros: The staff are very friendly and helpful, I had my pickup on the bus station of Pai on time. and Mr. 'Por' drive me to the GH and guided me to my room. He has very nice personality.
Cons: The Sun Hut is FAR away from the town. If you cannot ride on a motorbike, it will take you 20 minutes to the town on foot. And there is nth around the Sun Hut, if you want a drink or some food, you have to walk. Of cause, it would not be a problem if you can drive a motorbike.
The rooms are old, but in overall clean. the worst thing is that hot water is NOT HOT. It is pretty cold in Pai at night. So I have to take shower at day time. It costs 950 baht for a stream view hut. I think there are better choice there in Pai.
