Clean and extremely spacious flat. Nice balconies on either side of the building, so you could enjoy the sun all times of the day.
Convenient location: about 20m - 25m walk to the old town, 10m walk to Sagrada Familia. 2 minute walk to a tube station that connects you to anywhere else.
Very many nice restaurants within walking distance - from casual to high-end.
Carlos was very friendly and helpful both online and in person.
