At Casa Barcelo, there is always somebody at the reception 24/7. That was nice because there was always someone we could rely on to answer our questions about Barcelona! A group of friends and I (5 in total) booked this Airbnb. Upon arrival, we were told that we had apparently cancelled the booking (we didn't), but there were no further complications and we were promptly set up in an 8-person room with two other girls. We were given a tour of the hostel. This is a very nice and cosy place with a lot of respect for everyone staying there. Very homey, and reminded me of staying in a university dorm!
