We were really pleased with the flat and its location, and the information Cristina&Clara provided concerning the local area was useful.
Be prepared for traffic noise at night, but after the first night it became far less troublesome as we acclimatised to our surroundings and unnoticed by the end of our stay. Overall, a great place to stay, only 5 mins walk from the Sagrada Familia, with greengrocers and a bakery nearby.
