What could I say except that this place is just perfect. Andreas is the best host, incredibly nice and helpful. He showed us many great places, if you want to visit Barcelona, by foot, cycling, or metro, this location is the best one. The balcony's got a view on the Sagrada and a surprisingly quiet street for such a popular area.
The flat is beautiful, Andrea's design tastes are (to my opinion) some of the best one I've seen, from the bathroom to the living room, everything is stunning.
Don't hesitate, this is by far the most worst it airbnb i've been to. Thank you Andrea for being the perfect host !
