The apartment is conveniently located near La Sagrada Familia and public transport. It is a lovely and very well cleaned apartment.
In the apartment there is everything you need, maybe I would add a coat rack, as we had to leave our coats on one of the chairs.
However, it was a little noisy. We could hear slamming doors, and young people coming and go very late at night, singing, speaking and listening to music very loudly.
Maybe for a family with little children can be annoying. And for us in need of some sleep after a long day walking as well.
Definitely a place more suitable for young people/couple/friends. They can have fun and exploring the city well from there.
