Its very nice flat near the center of Barcelona. Marco was a super nice host and the communications was amazing with him! He also gave us a lot of tips where to go for what we needed. If you book this flat, make sure you are going to rent bike, because to the beach by foot its 1 hour. But with the Bike you have a lovely ride and you will see a lot of the city.
Right under the flat is a shop where you can buy food and drinks with a very friendly human being. you will also find a super restaurant at the opposite from the flat. And for you mornig coffe you have also a bakery.
The only thing was, that the washing machine was not working. Maybe we were not able to do it right:)
So thanks again to the Super Host Marco! He will answer your questions instantly and can give for everything good advices!
