I stayed here with some friends during a walking holiday in the Picos de Europa. While there's nothing basically wrong with the hotel, I found it to be rather uninspiring and I'm certain that there must be more nicer places to stay in the area.
The hotel faces on to a main road so make sure that you get a room at the back if you're a light sleeper. Single rooms were small, while doubles had more space although the bathrooms in all rooms were very cramped. The restaurant serves excellent evening meals at reasonable prices, but breakfasts were basic, two or three slices of toast (covered in olive oil) and a couple of cups of coffee served by the waiter. No diy buffet breakfasts here!
There's a nice terrace to sit out on during the warm evenings and a good sized pool. Potes itself is 20-25 mins walk away so if you want to eat or drink elsewhere, you've got to make an effort.
We paid 45 euros for singles and 60 for doubles - we got better for less in other parts of the Picos. In summary, the Infantado is good in parts and there's no problem with cleanliness, service etc. It's just so....... ordinary and I wouldn't go there again unless there was nowhere else.
