We stopped overnight here on an unplanned trek across europe after the volcano eruption. About the only bad thing I'd say about it was that there was an odd stain on the floor, but it did look like a red wine accident to us. We took a 3 person room which worked out at just over 60Euro. Shower was clean, powerful, warm and didn't leak everywhere. Could do with a mat though as it's a bit slippy on the way out. Beds were comfy, sheets clean and the room was very quiet overnight. There's free wireless internet available in the rooms which was patchy, but worked. The reception staff were friendly and helped us sort out food late at night and got us to the bus terminal in the morning. For info it was about 5 min walk from the train station to the hotel and only a few metro stops to the buses. Not sure how it's placed for city attractions however as we didn't stay long enough to find out.
If we found ourselves back in Bilbao we'd consider staying here for a while longer.
