Our stay at Xavier's was perfect! He and his wife are very welcoming and their apartment is fabulous! Besides being big enough to feel in our own house without disturbing the family, it is very, very well located in Barcelona. Not even 10 minutes walking to the Ramblas, la plaça de Cataluna or the Paseig de Gracia, and the subway is 5 minutes away from their place. What's more, there is a secure parking lot literally next door (59€ for 4 days)!
Even if Xabier or his wife don't speak english, you know what they say: A smile speaks all the languages!
