Josu and Irene were really great hosts. Communication was very quick and smooth, they gave us loads of great tips about things to do and places to eat in Bilbao and the surrounding region, and really went out of their way to be accommodating and helpful. The place itself is really well located in the old town, was very clean and had everything we needed. It is on a road with a lot of bars which can be a bit noisy at night on a weekend but we didn't find it a problem - the windows and shutters and pretty effective and they even supplied earplugs just in case, which we didn't need to use. Would highly recommend staying here.
