I wouldn't repeat, uncomfortable and crowded. Noisy.
Pros: It was one of the accommodations on our pilgrimage route to Santiago de Compostela, and the only thing I can highlight was the location. Cons: It was not a pension as such but a shared flat with people and a small kitchen where breakfast items were left in the fridge, some of which were even in bad condition. We paid for breakfast to avoid it. The bed was not comfortable, the mattress on the bed frame moved. And the noises from the other people didn't help to rest.
