The environment of the guesthouse is very nice, comfortable and clean. Trees around, so not feeling hot at all even though the weather is hot and we stay in fan room only. The room here is very big with two super single bed.
We spend another 3 night in Ta Som Guesthouse, which the location is nearby and the environment is good too. USD 11 per night include the breakfast also.Tour guide booklet, maps are available at the guesthouse. All the staffs are friendly also.
