Phi Phi Long Beach provides extremely basic accommodations on a gorgeous stretch of beach. Rooms aren't much more than concrete squares with fans, mosquito nets, and mattresses. The rates are a bit high considering that the rooms themselves are quite primitive, and can get extremely hot and stuffy when humidity levels and temperatres soar, but you're really paying for the soft white sand and crystal-clear water. Note that there's no hot water.
