We had a big party of 7 staying and it was comfortable to all of us. The vibes were welcoming and nice, it was easy to get around with the metro and taxis nearby. We felt secured in our building and our apartment with their high tech digital locks, on the other hand our bedroom locks did not work so that was a big inconvenience as we had to use our luggage to block the doors. There were windows in the apartment but they were so funny as they led to no where. Other than that the beds were comfy and the place was super clean. Would definitely recommend to any one visiting Barcelona with a big group.
