This is a fantastic modern appartment in a very bohemian part of town. The only dampener on our stay there was that it was during a week-long festival called Aste Nagusia. We had no idea. We were in Bilbao for Spanish lessons for my son. Fortunately the flat was far enough away from the music that we could sleep without any trouble. But the apartment is close to some dodgy streets so you must take care to cross the river at Puente de San Anton (by the old church) and not to head towards the train station or the streets Maiatzaren Biko or Hernani. If you keep your route to/from the apartment via the old quarter you will be fine. As for Aste Nagusia, well let's say I was very impressed with the hard work of the street cleaners every morning. Those guys are heros. Bilbao itself is a great city. I recommend the Museo de Bellas Artes over the Guggenheim any day.
