The apartment looks exactly like in the photos and lives up to expectations. It was tastefully furnished and well-equipped. We were a group of 5 friends who stayed there for 3 days and the apartment suited us well.
The apartment is very well located in Bilbao - walking distance to cool bars/restaurants and to all the main sights. There is a supermarket right next to the apartment and a great little meat / cheese / wine shop down the street.
The hosts shared a couple of google maps of places to eat and see as well as beaches outside of Bilbao - this was a great additional touch that we really appreciated!
