We really enjoyed our stay in the apartment! I think it's one of the best Airbnb flats I've stayed in!
The flat is really easy to get to from the airport by taxi, only 30 mins and quite cheap compared to London taxi prices. The check-in was super easy, and all automatic.
The flat is located in a great area, with a really nice bar/restaurant next door which serves good food for a quick meal if you want (not a noisy/busy restaurant, and it closes at 10pm so the flat is very quiet at night, and the flat is on the rear of the building). There's also a small shop and pharmacy right next to the flat too.
The apartment is also really close to La Sagrada Familia which you can see the top section from the window! It's a cool view from the flat. There's lots of great places to eat/drink/get ice cream around there, all only a few mins from the flat. The flat also has a bus just round the corner which takes you right to the beach in about 20 mins (or a 7 min taxi for around 7 euro). The tram is only a short walk too.
The flat has everything you need including a fan for when it's hot! The bed was super comfy too. Plus it's quiet at night so we slept well. It's really nice and clean as well.
Joan was super helpful too, and everything was setup via online check-ins, so it was really easy to access the flat using your phone.
I would definitely stay at the apartment again if I go back to Barcelona!
