We had a wonderful stay at Silvia's place! The apartment is nice and clean, and located in the best neighbor in my opinion. It is quiet and away from the touristy center but with tons local bars and restaurants around. It's close to the main eixample street and walking distance to most of the major spots.
Silvia is a wonderful host, she put a lot of thoughts into the apartment and tried to provide a great experience for her guests. Definitely recommend.
