We had a good time staying in Josu's and Irene's apartment. The apartment is conveniently located in Casco Viejo, with many of the city's highlights, restaurants and a tram- and metrostop close by. There are some bars located next to the apartment which gives some noise during the weekends, but it wasn't bad. Communication with the hosts was flawless, they gave us great information of things do to inside and outside of Bilbao.
