We stayed at Francesco's apartment for three days of our two week vacation in Europe and it was fantastic!
He arranged for a car to pick us up from the airport and bring us to the apartment. He was there to greet us even though our flight arrived early and we couldn't check in right away. Also allowed us to go up and store our luggage and get changed after a long flight. He gave us plenty of information about the city (maps, coupons, advice on where to eat, etc). He even left us a bottle of wine in the fridge! The apartment was on the top floor of the building and on the last day the elevator was broken. Even though it wasn't his fault he constantly apologized for the inconvenience and helped us carry our luggage down the stairs. Overall Francesco was a fantastic host and we would stay with him again in a heartbeat!
As far as the apartment goes it was cute and cozy, exactly what we needed. The terrace was by far the best part, the view every night was stunning making our time in Barcelona especially memorable.
