I stayed with my 10-year-old son at Bilbao City Room for a two-night stay in the city. It was a perfect location to visit the Guggenheim Museum (walking distance). It is also a walking distance from the train station. The rooms are comfortable and clean, but if you tend to suffer from the heat, note that there is no air conditioning in the room. Ours had a ceiling fan and the window opened on a quiet courtyard. If you're looking for a good restaurant nearby and feel for Mexican food, try the Chilango.
