Everlasting appears to be a low cost hostel of thatched roof bamboo cottages in a small compound. These are located in Nang Rong.
It is at 7 Prachasamaki Road. The phone is (66)44 624-224
Various internet listings for the Louis Guest House appear under “Nang Rong hotels/hostels”. It it appears to be about 15 km to the south on the road to Lahan Sai (which is a nice rural area of Thailand). I list it here because internet entries may lead some to believe it is located in the city.
It is easy to see why Thailand has long been a major vacation place for the entire world. The people here are friendly in a way that is in marked contrast to other destinations in Asia, and it gets even better outside of Bangkok and the major tourist areas.
