Although we haven't met Pilar her friend Ramon received us at the apartment. He explained us everything and was a good welcome to Barcelona.
The apartment is exactly as in the photos, very clean and the Gràcia is perfect. There is everything near by 5-10 minutes walking (metro station, market, bar, restaurants). There is a lot of information from the city at the apartment and Pilar gave us by email as well.
We had a problem with the apartment keys (we made a mistake and closed the door with both keys inside). We contacted Pilar and she provided us a spare key to go inside in a short noticed. She was really helpful.
I highly recommend this apartment and will definitely come back!
