First, the hostess was excellent and friendly; she left us a bottle of local sparkling wine that we enjoyed, and she gave us a list of the best restaurant in the area. The Career de Blai, that she recommended, is a wonderful pedestrian street full of excellent tapa bars, with locals and very low price compared to La Rambla places.
The apartment is perfect, and very cheap compared to other in the area, but expect to climb four floors. The apartment is beside a subway station, and the funicular to Montjuic. You can go to the Sagrada Familia by the subway, or the other main attractions of Barcelona by walking 20 minutes or less.
Finally, I have to talk about the Arab restaurant downstairs, Ouzoud. When we had a phone problem, the owner of the restaurant, Mustapha, kindly help us. The next night, his wife warmly received us for a wonderful meal. And after that they were always at the door of the restaurant for a little chat. They will be happy to see you, and Mustapha can talk in Arab, Italian, English and French!
