Our stay at Isaac's place was fantastic, we were warmly greeted by Issac, who kindly showed us lots of areas on our map to visit, both within Bilbao and along the coast, where we would be heading later that week. His house was spotless, welcoming and beautifully decorated. It is also in an ideal location, only a 5 minute walk from the old town, (but still quiet at night) and 20 minutes walk from the Guggenheim. Isaac is a wonderful host, and would highly recommend staying at his place.
