The location of the apartment is simply perfect, in a beautiful street full of restaurants and bars, close to the underground and with the main commercial streets of Barcelona only few blocks away. The building is beautiful and the apartment itself is comfortable and enjoyable, although some elements such the door handles and the floor tiles in the bathroom would need a bit of refurbishment.
The communication with the host couldn't be any smoother, so all in all it was a very nice stay and I'd recommend the apartment.
