this is the best place with the best people that you could find in your trip or whatever it is!! The house is like an art gallery and music, the room is small but functional, perfect for couple, good bathroom and kitchen equipped.
I suggest to speak and ask a lot to Zarata, because she can tell you all about Bilbao and the Bilbains. Her flatmate and she, are the best people to share a flat, even if they are just few days ;)
