Julia's apartment was really nice placed as we had only 10-15min to Parc Guell and also to Sagrada Familia. All you need (cafes, supermarkets, train stations) were very close to the flat.
We felt really good in there as beside a proper coffee machine we had everything within the kitchen for cooking.
it was also a plus that every person has his own privacy (3 different rooms), but on the other hand the room closest to the entrance did not catch the wifi signal.
