We had a very pleasant stay in Caldes de Boí. The hotel is well equipped, with 3 swimming pools and a bar by the pool, a reading room and a living room both very cozy. Our room and our bathroom had a pretty good size. The staff, specially from the bar&restaurant were very kind. The hotel surroundings are amazing, plenty to do, walk around in their gardens, go for a short walk to the spring water fountains by the hotel, walk some waterfalls nearby... It is a beautiful spot and if the weather is glorious, it is like paradise. My only negative comment is regarding their WIFI, was very weak and in some parts of the hotel worked on and off, not reliable. It needs improvement. I cannot comment on the spa services since I did not use them. In general it was an extremely positive experience.
