I was in Nong Khai the other day and decieded to stay at TONYS BAR on the far side of the walk though market. We had looked at the rooms around the corner which were 450 bht and total crap.
Anyway for 1200 bht a night you get a nice big room and large bath room as well as big screen TV with sat TV, Fridge lounge and a huge view of the river. I could even watch the river while have my morning crap
Food and service was very good and came with a smile and the beers were always cold
So if you are looking for a good place to stay in Nong Khai next time try TONYS BAR
