Had a fantastic stay here! Great location, walkable to the beach and Ciutadella Park and lots of transit options to other parts of the city.
Rooms are beautiful and the beds are comfy, with USB chargers and lights in each bed and handy lockers right underneath each bunk. Felt like a very secure building as well.
The lounge areas--on the 2nd floor and rooftop--are beautiful and comfortable. I didn't engage in any of the social events but heard that they were great as well.
I'll say that it was not a party atmosphere in the rooms or very social at all. This was GREAT for me as I was mostly using it as a place to sleep. Everyone was very considerate about noise getting ready for bed and sleeping at night but mostly did their own thing. If you're looking for more of a party social atmosphere, perhaps consider another hostel or taking part in the social events they have planned!
