I stayed here in the off-season and so the price was 300 Baht a night per bungalow - amazing value for money.
The Bungalows are very cute and I guess perfect for couples - try to get one on the riverfront. They consist of a little bedroom with an onsuite bathroom at the back and a porch with hammock at the front. They are a fair size for socialising - can fit about 6 of you comfortably on the porch chilling out. They are secure and also there is always a member of staff monitering who comes in and out so it's quite safe to park a motorbike outside.
Lovely little place, well worth a stay.

Vila de Pai offers nice bungalows in a quiet setting but still within the center of Pai. The property sits along the river with beautiful, lush landscaping, making this guest house feel higher end than the price would suggest. The bungalows are not fancy but a bit more than basic and the management is friendly...best of all, there are hammocks on the verandas. There are plenty of restaurants and bars as neighbors but the music you might hear at night is just that, and not "noise". It's really a great place and I look forward to visiting again sometime.

I stayed for one night at Villa de Pai and wish it could have been much longer. I was placed in a bungalow with a queen-sized bed and an ensuite bathroom for 200 baht / night. It had hot water and a mosquito net, though I didn't need it. Really clean; great location at the end of the main street. There's a FANTASTIC hippie restaurant across the street with loads of vegetarian and vegan options (and walls of wheatgrass). ^^
