The apartment is indeed close to the metro station in a residential neighborhood, and close to the Vatican by foot or metro. The green room is as described, very clean, with an en-suite small but practical bathroom. Giorgio is a perfect host, offered to meet at the metro station to help with heavy luggage, and he makes his guests feel like they are visiting a friend who has a spare guest room in Rome ! I stayed 2 days and wished I had more time to discover Rome.
