It wasn't what we expected. Very small but comfortable. It's basically living with a family under their roof. Shared bathroom between I'm not sure how many others. The location isn't particularly close to the centre but you can easily drive, taxi, bike or bus it in.
Luis is a fantastic, kind and giving person - he gave us a complimentary mini bottle of cava. The general vibe of the place isn't for everyone. Just be aware that this is good for one night and then move on.
