A couple of years ago I stayed at the Refugi Pere Carné with some friends for a long weekend of skiing. We had a 7-bed room to ourselves, use of shared facilities, breakfast and evening meal for the bargain price of £20pp per night. The facilities are clean and warm, the beds are comfortable and the staff very friendly. There's a small bar on site and a fire to make it cosy.
I'm actually planning a big group trip back to the same place for next year.
The only downside is that the ski lifts at La Molina are a few kilometers from the refuge meaning you really need your own transport, although I understand there is a bus service. As the hotel is quite isolated evening entertainment is limited. As I said before, it's perfect no-frills accommodation for a budget ski break.
