I stayed in 3 places in Pai. This was the cheapest, simplest, and closest to town. Staying in a bamboo hut just over the river from town was great. The walking street is just over a bamboo bridge. No AC, but the fan was fine. I had an ensuite that was decent by Thai standards. The balcony area with hammock was great for chatting with people I met. Fairly quiet, too. Tip - bring earplugs, as bamboo walls won't block noise from other huts (This tip applies for anywhere in Thailand, actually. Scooters, music, etc.)
