Mario is an awesome host! His house is truly ideal and perfect for us to explore Rome deeply. The neighborhood is safe and close to the Metro station. Mario is super welcoming and nice. He showed us the map of Rome and he suggested a few places that he thought might be awesome for us to visit. I would definitely go again if I were to visit Rome again. I am truly sorry that me and my friend caused a lot of trouble for you, Mario. Thank you for coming home for us with the key! Hope some day we can meet again and talk more about art!
