The hotel was made up of efficiency rooms, with 12 units on each floor. Ours had space for all 4 family members, with 2 twin size beds and a pull out couch. (Unfortunately they were all rock hard and we woke up stiff each day, but we were walking about 15km each day so we would pass out anyway.) The furniture was simple but serviceable. There was a parking garage and grocery market next door, which made it easy to grab drinks and snacks to keep in the room. The room had a very functional mini-fridge and microwave, which made getting ready for the day a bit easier with a family. The front desk was helpful when we ran out of items such as bathroom tissue and soap, or needed to have them hold bags before/after check out. Just note, they ask you to leave your key with the always manned front desk, so it does not get lost while you are out and about.
The location is a bit further from many of the sights and activities of the city, and since Barcelona is so spread out it can take more time to reach your destination. However, Barcelona has a very efficient and easy to use public transportation system in its busses and metro, and the hotel is close to several stops within a 5 minute walk. We would stay here again.
