I spent 6 nights at Gianmarco's place during a visit to Rome. The apartment is well-located, not quite in the center of things, but within walking distance to nearly everything - the center of Rome, the Vatican, the Villa Borghese, etc. If you don't feel like walking, there are also many bus routes nearby, and the SITBus to the airport drops off and picks up just a few blocks away, so it's very convenient. Gianmarco was so helpful with directions and suggestions for my trip and he always responded to my messages right away. The room included a small breakfast at the cafe downstairs, which was a great benefit. I would definitely recommend staying here on a visit to Rome!
