I didn't hang out in the social area of the Hostel much. But it seemed a nice atmosphere.
Also I learned that this was a "legal" hostel while there seem to be many hostels in Barcelona with no permit.
1 small point for the German boy who is going with groups from the hostel to shows, Fountan ( sorry, I forgot your name). It is better not to say to the people "let's stay more in this bar, because they are paying for me 15€ for every hour when I am with a group". It is giving very bad impression.
Everything else was excellent.
