The apartment is great, and has a nice view of Tibidabo church, specially at night.
It's in a very central location, with easy access to the subway and to several bus options. It's also close to Plaça d'Espanya, and to several restaurants, supermarkets and bars.
Albert and his family are also very attentive! They explained us how to move around Barcelona from their home, and gave tips about the nice places to visit.
