A perfect place for discovering Bilbao (Bilbo) The Attic was really clean and cosy. We felt at home at once. Even if its in the heart of the old city it was no noice disturbing us.
We did a guided pintxo tour the first evening. That was a good way to find out about the area and the food.
Also will recomend the Kasko restauarant, it is run by Miriams brother and we were welcomed as we were family.
Daytrip by metro to Plentzia beach can be recomended. (I am not speaking about Guggenheim as this is mandatory) The funicular also gives you a good wiev of Bilbo on a day with a clear wiev.
Will come back.
