We had such a great, week long stay at Aitor's place. He was incredibly helpful both before and during the trip, and always responded to questions extremely quickly. The apartment is in an ideal location, and is an easy walk to most of the sites in Bilbao. It's also very close to a taxi stand, the light rail and the metro for farther-away sites. Bilbao is absolutely amazing, we are already trying to figure out how to get back!
