The entire experience was perfect; Alexandra came to meet us and give us the keys, provided us with a list of nearby shops and restaurants that came recommended, and setup a ride back to the airport for us on the last day. The apartment itself was beautiful; very modern decorating, very spacious, and fit all six of us with room to spare. It even came equipped with toiletries, such as shampoo, conditioner, soap, toothbrushes, and even slippers! It is located less than a five-minute walk from the L3 Diagonal metro station (take the L3 line; it's much closer than the L5 Diagonal stop) and couldn't have been in a more perfect area. It was very central and only a short metro ride to every major tourist attraction you would want to see. The traffic and trash pickup outside can get a little loud at times, but I expect that's the case with most places you would stay in Barcelona. The owners will setup a ride to and from the airport if needed. We took the metro from the airport to the apartment on the first day, which was cheap and took about an hour. The way back to the airport, they set up a cab for us, which came to pick us up right on time and cost 59 Euro for six people. It was truly an incredible experience and my family and I were extremely satisfied with how everything went.
