We stayed at the Viengtai hotel for 4 days at the beginning of our Thailand tour. The hotel is nice enough. Bedrooms are a good size and the triple bedroom was very comfortable. The breakfast was good and staff were accommodating. Although the hotel is located just a road from Kho San, we did not hear the noise at night.
The only disappointment was that there was no lounge/bar within the hotel where we could enjoy the occasional drink together after a day out. We travelled in a group of 13, and split up most days, so this was a problem. The pool area closes very early (8pm) which was disappointing. Overall, a good stay, good location, pleasant staff.More
