Roberto is a great host. Very easy to talk to and nice. Very acommodating. We arrived at 1am and there was no problem for him to let us in! He gave us all info we needed and he checked during our stay to find out if we were ok.
Apartment is located 5 min walk from the supermarket and Barcelona Sants-big metro and train station.
It's extremely quiet and that's really important as Barcelona never sleeps.
