Alex is a very responsive host, we have no problem with communication. He was helpful without being intrusive.
The place is right in the center of the Old Town of Bilbao, located along one of the famous Siete Calles in Bilbao, a two-minute walk from the La Ribera Market, old churches, shops, restaurants, groceries. The apartment is located at the first floor (floor above the ground floor; to Americans this is the second floor) so there is a flight of stairs to be navigated. That was our only problem because of our heavy luggages :). Otherwise, we had a great stay, thank you to our host Alex.
