After a 6 months stay I recommend this apartment. Very well placed in the Sant' Andreu district, with easy connection to the center of the city. The apartment is very luminous and pleasant mostly for the terrace.
Manuel is receptive and will help you for any thing.
The only little issues I had were for the car, quite difficult to park in this district ( in the rest of Barcelona as well ). Also the wardrobe is quite little for a long stay but it can be overcome.
