We have spent a couple of nights in this apartment during our stay in Barcelona. The check-in was effective and well organised. The whole of the house is nice and clean but there are few points to highlight. The house does not have any carpets so I would suggest bringing your own slippers. The kitchen is extremely well equipped but there were small flies flying around due to an old sponge been left on the surface. You can hear the neighbours activities every time! And so I guess they can hear you. Not the best thing to have when you're trying to spend a holiday with your significant half.
Those are the only negative points that we encountered during our stay, rather than that, very good place to stay. Near to everything, transport, attractions, extremely equipped etc.
