We stayed for two nights in Bilbao. The room was lovely, just like in the photo, with a small terrace and fantastic views over the river and old town as the flat is on the third floor.. We shared a bathroom with Judith and her sweet little son, which worked out fine.
The location is perfect on the river, a stones's throw over the bridge from the old town and 20 minutes walk from the Guggenheim. Easy to get to on the tram.
