Marco and Olaia were very welcoming. Communication was fine before arriving to set up a time to meet at the apartment, which was very easy to find from the airport via a short bus to the main square.
Marco was there to welcome us and give us advice about the apartment and some great restaurants and travel tips.
The location is fantastic for the main Bilbao sights and the old town was just a short walk. Highly recommended and thanks to Marco and Olaia for being so nice and welcoming!
