The apartment is small but okay for two persons. Our hosts were easy to deal with and always reachable. We got sooo much useful information about Barcelona per e-mail in advance. The view from the apartment is amazing, there is a roof terrace as well. Parc Güell is in a walking distance of 20'. The bus station at the end of the street serves two important bus lines which take you directly close to the Sagrada Familia, to Casa Mila & Batllo, to Plaza Catalunya and to La Rambla. The 3G internet device is useful for messaging but not for surfing, but it is portable (battery for half a day). We would certainly stay there again.
