Laia and Aleu's apartment in Gracia was perfect for our trip. Our party of 3 people also travelled with our bicycles, so we had a lot of stuff on us, and the apartment was still large enough and comfortable for our needs. I do think it would be hard to imagine 5 people in that unit: my advice is keep it to no more than 3 people (otherwise people are taking up the living room). The apartment is close to everything you really need (Metro, grocery store, etc.) and we were able to pleasantly walk everywhere we wanted to go out for dinner/drinks. Overall it's a great unit and no complaints!
