We were welcome to the apartment by Mar's brother. The apartment is lovely and easy to get to from the airport (the Aerobus dropped us three blocks away). We really loved the neighborhood--ate most of our meals within a few blocks of the apartment. The area felt very residential (not touristy) but it was a quick walk to Las Ramblas and other popular destinations. Mar left a nice packet of information and many books/magazines on Barcelona for us. We would be happy to stay there again!
