I had a single room and even though it was small it was very clean and modern, a very comfortable stay. The location is unbeatable, it's right where Liceu station is and is amongst a lot of attractions and good eats, very walkable and well connected. Staff were courteous and were around 24/7. Please note this doesn't have a kitchen area or a laundry service (if that's important to you), but there are a few laundromats nearby that were reasonably priced. It's not a hostel to meet new people either (again if that's important to you), I noticed there were families, older people and couples, people just kept to themselves. I didn't mind this at all, but something to think about if you're seeking the more usual hostelling experience.
