Amazing place, very cozy and feel like home, have everything you need in kitchen and around the house, It was little cold during our stay in Vatican but the heater in the apartment works so great that we have to open the windows from time to time, beautiful patio to chill with romantic lights, 7 mins walk to the metro line which can take you to Rome within 15-20 minutes, we love the area with grocery store right down the building and few restaurants around.
Roberto help us taking millions of our luggage up to the room, he also helped during our stay in regards to trains schedule,best restaurants and other places to visit and enjoy. He also allowed us to check-in early and very friendly. He also arrange a taxi for us for our early flights. He also have gifts for guests so be ready :) (little secret) I could have given more stars if there are more. I definitely recommend Roberto's place if you go to Rome/Vatican.
