We were 6 people having a trip in the north of Spain and we really enjoyed our stay here ! The flat is really nice, and it is nicely located (3 minutes on foot to a lovely park).
Xabi & Almu were really quick to answer, and when we arrived, their friend Alex (in charge of lending us the keys) told us everything about nice places all around Bilbao ! As it was our first time, it was more than welcome :)
