Sam's flat is a great spot if you have a large group and want to be based in central Barcelona. We were here for a Barcelona match and it acted as a great base for us. It's a really big space and it's great as there is plenty of room for our group of 10 (there was space for a couple more!). The walls are fairly thin, so if your group is noisy you can hear what's going on at the other end of the flat, but it doesn't detract from the flat - great value for money.
