The apartment really is perfect - one of the very best AirBnB stays I've ever had. Comms before I arrived and throughout stay were excellent, the place was spotlessly clean, and the location is just about the best you could ask for in Barcelona. The view of Sagrada Familia from the apartment itself, and the rooftop terrace, is even better than the pictures.
Really, there's not a single thing I could fault throughout my whole stay, and I do hope to return soon.
