The appartement of Aitziber is very nice! It's perfectly situated in the center of the city. We came by car but we did not even need to take it during our stay, as everything is just near: museums, places of interest, restaurants, shops, etc. The appatement is so nicely decorated and cosy, it's really authentic. We have also appreciated the advice of Aitziber about the places in Bilbao. I definitely recommend you the place.
