The Airbnb is in a very nice area. There are a lot of shops, bars, restaurants, … which you can reach in walking distance. The metro is also very close (8min walk).
The appartment is big and has everything you need for a longer stay. Also the small terrace was really nice and quiet.
Alex gave us a lot of good tips where to go in Barcelona. Unfortunately we had to leave Barcelona way earlier than planned - changing the date was uncomplicated and Alex was very understanding. I hope we can visit again some time.
