Marco was a great host. He reached out to me with instructions on how to get to his place including which bus to take from FCO airport. Was fast at responding to questions and provided great recommendations on local restaurants.
His location is great if you plan to do a lot of things near Vatican City (e.g., Sistine Chapel) because it is only a 10 minute walk there. He is nearby a lot of great restaurants (some even as close as 3 minutes), beautiful neighborhoods, and you can walk to pretty much everything if you like walking. The whole time I stayed, my wife and were able to walk to all our desired sightseeing things like Vatican City, Colosseum, Spanish Steps and Trevi Fountain.
Marco is great at making you feel at home - he even cooked us a home meal for my wife and I and we were able to bond over our lives and share stories! Highly recommend!
