Giorgio was a great host! Very friendly with alot of usefull information. He is located just across the street from the metro rail station if you want to take the train anywhere. He will provide you with a map of Rome that shows the rail path as well as the city attractions. The vatican was one or two stops away I think or it is a short walk away ( a little over a click or 1,000 m). It was very easy for me to navigate from the Scala di España to the Trevi Fountain and the Panthenon on foot with the map provided. There are two great places Gio suggested for pizza and a nice bakery nearby, all within walking distance. There are plenty of icecream shops along the way to the vatican as well as a couple of döner shops. For anyone traveling to Rome, I recommend staying with Gio due to him being a great host, close proximity to the vatican and easy access to public transportation. I also recommend buying the omnia/roma pass as it will get you access to the vatican museum, st peter's basilica, and the sistine chappel with out having to wait in the long lines. It will save you alot of time. You don't have to book a tour unless you want the in depth experience with lots of details. You can also use the roma pass to get into the colosseum and another roman attraction on its list as well as use it for public transportation. Once you activate it, it is good for 3 days. The room was as shown in the photos and very comfortable and cozy. If you drive there like I did, parking is available at the trainstation or at the top of the road where Gio's apartment building is located. I had a great time staying with Gio and visiting Rome and I recommend him to anyone with plans to visit Rome
