We really enjoyed our stay at the place. Eduard was our host and he is very communicative and helpful. We had to check in early and he helped us store our luggages at the apartment first while we went out and wait for the apartment to be ready. He even let us checked out late since our flight is in the evening, when there wasn't any new check in that day.
The apartment is great. It is very clean and has a lovely spacious terrace as pictured. There is a metro station, supermarket, and some stores close by. It is walkable to go to the Las Ramblas and Plaza Catalunya, even if it's not as close as I first imagined. We also love the well equipped kitchen and unique setting of the apartment!
