Ana is a nice and friendly hostess and speaks English well. She greeted us after a long and late arrival. This is a great location with plenty of local cafes, bakeries and grocery stores. It is a short walk to Sagrada Familia and other local attractions. Bike rentals are within walking distance and we biked to the beach and toured some of Barcelona in about than 3 hours. There are easy connections to the subway and bus systems. The kitchen and bathroom were functional and adequate. The living room space was quite comfortable with a large table for dining, laying out maps, gear etc. Ana was responsive to our needs and was only a text away when she was at work. Otherwise, Ana is right across the hall in a separate, connecting apartment (with a shared foyer).
Note: While the post says sleeps six, we found the flat to be smaller than anticipated and felt it would only be suitable for two adults with two children.
