I stayed at Gabriela's apartment for a month, I was very comfortable there and Gabriela was really helpful and a great host. The apartment is well connected with Barcelona city but the area between Sants and Les Corts offers an experience what it is like to live in Barcelona where the locals live and not just where the tourists stay. Sants station is very close which provides great connections to the city centre of Barcelona and to many locations and cities outside of Bcn. One of the best things for me with this location is the proximity to Montjuic which I think is one of the beautiful places in Barcelona. The apartment is close to many supermarkets, bars, restaurants (in this area I went to more in Sants than Les Corts) and cafes, there is an Ametller Origen right next door to the apartment building which is an expensive but amazing supermarket and bakery/cafe. The apartment is also well located for getting a taxi to and from El Prat airport.
