Location, location, location. Despite being only two blocks away from La Sagrada Familia, the neighborhood has a local and lively taste, full of family businesses, restaurants and coffee shops.
The description of the apartment is accurate, we found the place clean and in good condition, and really there is very little to complain about. Maybe the noise at night, but then again, you can't expect any different when you are living so centrally in such a lively city.
