I know others have written about the hostel here which doesn't sound too great, but I can only talk about the bar which I think is in about the most unbelievable place imaginable. We were making our way to Sos del Rey Catolico in the car from Jaca along a really dreadful road with pot holes everywhere and we suddenly came upon this place which looked like a ghost town. We stopped and looked on the map and there was nothing on the map for here. We got out just to look at the ghost town, turned a corner and there was a bar! With people in it! We couldn't believe it. So this review is really based on us having drinks and a few tapas in an extraordinary situation. Top marks for the 'servicios' though. Apparently this town was abandoned in 1959 because of them building a reservoir which flooded the farm land people here worked on. Some rehabilitation of the place is taking place, including turning some of the old buildings into a hostel for pilgrims on the Camino de Santiago. You can see parts of the original paved way here.
