Alex, Javi and Pilar are fantastic, they took, Pilar gave me tips about where to go in town and (where not to go) ;-) best places to visit, how to use in-house devices, double keys...
The flat is well located, if you come for party don't rent a car it is useless as Barcelona is quiet big, the flat managers are super friendly, and communicative, they are just amazing! THANK YOU GUYS!
