We stayed at Sarah's place for Barcelona marathon weekend. Place is 5-10 minutes walk from Sants station so very easy to get to from and to the airport. Metro stop next to the apartment quarantees easy access to anywhere in the city. We were greeted by Camila who was really friendly and gave some great local tips on where to dine after the marathon. Apartment is very clean and we loved the big open space there. Definitely recommend staying here if you're going to Barcelona!
