Great location, we walked everywhere (Sagrada Família, Park Güell, beach, Font Màgica de Montjuïc (magic fountain), Teatre Grec y Jardins del Teatre Grec, Casa Batlló).
Billy Brunch & Garden is a 7 minute walk, amazing scrambled eggs, and a friendly cat named Chochi who hangs out at the tables at the back of the garden.
Andre is very friendly and will send you lots of suggestions for other local delicacies and activities.
