Ana and Pablo's flat is definitely a very nice place and very well located to visit Barcelona. It is close to Placa de Catalunya that is a hub for all public transports... and at a walking distance of many strategic points: shops, Ramblas, the beach, Sagrada Familia. It is beautiful (see the pictures) and very well equipped (shelves, dishes, towels,...). It is very spacy and organized in such a way that our two families (4 adults and 6 active teenagers) managed to live here together for 5 days, ... peacefully! Ana and Pablo had a lot of attentions (directions to reach the place, advices... And a welcome pack :) that made this stay a total success. To reach the flat from the airport, the aerobus, suggested by Ana and Pablo, is definitely the simplest and cheapest solution.
