My colleagues and I spent a weekend at Roua Muntilor and we liked the place very much. The sight is very beautiful and relaxing, rooms are clean and they look nice, and the staff was also very nice to us. They have a pool with warm water (32 or 34 Celsius), jacuzzi and a room for playing games (ping pong, soccer, billiards). The only inconvenience was the railroad which is situated near the pension, but the trains don't come very often there though, so it was not that bad.
I read a comment above and someone said that they had to go to sleep when the staff told them so. For us it was not the same. Everyone went to sleep any hour they wanted (some of us went to 10 PM, others at 1 AM, 4 AM, etc).
The time spent there was worth it for so I highly recommend it.
