Aitor is a very nice and friendly host and the room was very comfortable. Bilbao has become one of my favourite cities in Spain. I had a very comfortable stay in Aitor's place for two nights. The position is also great. It's within 5 minutes walk to the Metro and within 10 minutes walk to the train station. I walked to Guggenheim museum, which was only around 15 to 20 minutes and it was a very pleasant walk.
