I have stayed at many Airbnbs, in many different countries - but by far staying at Marcela and Josep's home was my favorite. I felt welcome the first moment I arrived, and the atmosphere was warm and fun. I loved sharing breakfast with the family, meeting their kids and playing with the kitty! Marcela and Josep were wonderful hosts.
The flat is just as described, and the location is beyond perfect - right next to Sagrada Familia, and if you're like me and you love walking (a lot), you can walk everywhere from here. Or take the metro;) which is located just a few minutes from the apartment.
