I would highly recommend staying at Joseba's if you are visiting Bilbao. The accomodation is clean and smells great (there's lots of lavendar around). Joseba was not there when we stayed but his girlfriend Joanna stepped in, and she was delightful! We were even taken on a walk to see the sunset, we got to try some wine and olives from Joseba's farm and had fresh orange juice every morning! The location of the accomodation is perfect, we were a stones throw away from the Guggenheim and it was easy to get to Casco Viejo and other attractions.
