It was my very first experience using airbnb to find a place to stay and I was positively surprised when I stepped in Maria's apartment, because it was more beautiful and big than on the photos! There are two double bedrooms with bathrooms and one single bedroom. There is a third bathroom next to it, however it is very small, difficult to use its shower. But this third bathroom wasn't mentioned in the description of the apartment, so we were surprised finding it :). At the check-in Milly has greeted us and explained everything. Even some food, fruites and drinks were prepared, which was very lovely. Apartment and everything in it was very clean!
Maria gave us very good and detailed advices about sightseeings, places to shop and to eat.
Location is great. 5 minutes walk to Sagrada Familia. There is the metro, which has a very good system in Barcelona. If you like walking, you can walk even to La Rambla, as we did often. Don't miss to walk in beautiful streets of Vila de Gracia.
I think the isolation between apartments is not very good, so that we heared noise from upstairs as in our apartment, but it was only once and during the day. If I come back to Barcelona, I will stay at the same, Maria's place!
