Seeing as though we survived off their vending machine the first night, not realizing things would close SUPER early around the holidays, it's almost enough to warrant the four stars on its own. But snacks aside (though olives and strange waffles? I like your eccentricity hostel humans.) this is a fairly decent option for a budget hostel.
IMPORTANT POINT - I said: BUDGET hostel.
Definitely don't book here hoping for anything grand. The space is very very basic and when we arrived, in the midst of repair, so a bit hectic. The room was plain: two simple beds, a desk, a safe and a shower that worked. There are no bells and whistles - it's very much like staying in a dorm room.
BUT it was clean, the folks who work there are lovely, they had a little common space to make tea, etc and we were able to book a private room with a private bathroom for under £40 a night. So if you're looking to explore Bilbao on a dime, this place is safe, centrally located and has weirdly wonderful waffles in their vending machine.
