Silvia is a wonderful host. Before my arrival, she sent over detailed emails with clear instruction of directions to her apartment, and also tips of visiting Barcelona. The apartment, as described in the bnb page, is right in front of Sagrada Familia, truly close to the metro station, and a Carrefour Express. The room is small but cozy, and Silvia being a tremendously helpful host is a great plus, she's always around answering questions and advising on how to make the most of Barcelona.
