The apartment is just as it appears in the pictures and had everything we needed for a short stay. It felt very safe. We arrived relatively late in the evening (10:45) but were well greeted with some helpful information/tips about places to visit.
The apartment is located very close to La Sagrada Familia as well as a Metro stop and many bus stops.
The apartment was just a little noisy at night from the street and apartment upstairs. Overall a good base for our short stay.
