I was very pleased when I arrived at all Iron hostel. It had a cool and relaxing atmosphere. The staff is very easygoing, caring and friendly. All facilities are in good condition and very clean. Location is almost on top of a hill (so take a little "exhausting" walk of approx. 10min into account).
If I ever get back to Bilbao, I'd definitely come back here. Very much recommended.
Thanks for hosting me!
