We checked in quite late and the staff was incredibly welcoming. You could tell the Hat was not like any other hostel. Very comfortable, tasty breakfast, lovely staff, clean, very central (2 min walk from Placa Mayor). We had trouble with our reservation the first night and Alfonso found us an alternative immediately. It was the highlight of our trip to Spain. The rooftop bar/terrace is a great place to meet people and make new connections. Their Mojitos and empanadas are simply great. We would definitely stay there again.
