Really important: this is a reference for Oudomphong I, not II. Be sure not to get confused looking for number 2 and end up trying the Number 1! Be careful: they have the same address.
It is a real shame that I have to write this because the rooms weren't that bad, fairly clean (not the cleanest of course) and we had free bananas and tea everyday, plus wifi. BUT it is also important to mention this:
When we first got there asking for a room, they told us a double room with shared bathroom was 80.000 kip and with private bathroom 100.000 kip. We took the shared bathroom for 2 nights but got REALLY sick and had to stay 2 more nights on a private bathroom one. This last one was a room right next to the reception and we could hear during 2 days how they said different prices to different tourist who came asking for rooms. They would change dramatically the price for the same room according to who was asking!!! And we were checking out they were trying to charge us 120.000 per day for the room the told us was 100.000!!
It was definitely disappointing to realize that we were dealing with dishonest staff...
