Roberto's apartment was really nice - great location with a view of the Museum Nacional d’Art de Catalunya on Montjuic directly from lying on the bed! Big plus was the nice and quite big terrace. The apartment is a 15 minutes walk to Place d'Espagna and only a couple of minutes from a metro station.
We were welcomed by a friend of Roberto at the apartment who showed us everything and gave us suggestions for things to do & see. The apartment was really clean, quiet at night and had everything you need for staying there. Can highly recommend it!
