We stayed more than a month at Oliver's place and fell in love with both the apartment and the district. Sarria is one of the best neighborhood of Barcelona so you can be sure that you will like it. It worth to mention that it literally takes 15-20 mins from the apartment to the city center by train. The apartment itself has everything you need plus a lot of light, charm and privacy since the building is small. As a bonus you have the access to the rooftop where you can have a barbecue or just enjoy evening atmosphere of Sarria. The communication with Oliver was quick and efficient. I highly recommend this place. You won't regret!
