Even if my stay in Bilbao (and in Aitor’s apartment) was very short, rarely I had an accommodation that ran so smooth. The location is right in the centre, walking distance from most of the city’s attractions. The apartment was very clean, even if I arrived earlier than the check-in was foreseen.
If you book a room in Aitor’s place, you even get a map with the best places to eat, drink and hang around. So useful!
Btw, across the street from his place is probably one of the best refurbishments of a cultural building I have ever seen so far. Don’t underestimate Azkuna Zentroa, the building right in front of the apartment.
