Great apartment, has everything you need and is a tad tight for 8 people. A bit far from the city center, but if you buy a metro pass then its not a problem at all. Otherwise it's an hour walk.
You have to check in at an office that is in the city center, which is a bit inconvenient but they hail you a taxi to get to the apartment which is nice, free of charge.
It's got a great balcony and was everything me and seven of my friends needed to have an exceptional stay in Barcelona. Thank you Eva&Jacques!
