The apartment was recently renovated, and was comfortable, spacious and quiet. We appreciated the bus to the beach right by the door, and the ability to park the car in the street for free. Public transportation was close enough, and it is just 15-20 min to the city center. There are several chain-supermarkets nearby too.
The area was very quiet during the day and night (and that's not easy to find in Barcelona). The incredible views from the rooftop terrace more than make up for the hills in the area and the four flights of stairs to get to the apartment (we're a young group so we don't mind).
Borja was a great host, always available, very attentive. He took care of everything we needed quickly.
