The apartment is in an excellent location with many restaurants, cafes and shopping all within walking distance. The metro is also within walking distance and there is a bus stop right outside the front door. The host, Fabio, was very responsive to our questions, and as noted by other reviewers, provided assistance with scheduling a taxi for pickup at airport (huge help) and stocked the kitchen with great snacks and basics like OJ, milk, coffee, tea, etc. We had everything we needed and it was a perfect location from which to visit the Vatican (walking) and every other part of Rome (using the excellent metro and bus system).
The apartment is very clean and provides 3 spacious bedrooms, each with its own bathroom, a common area + kitchen and a great balcony with views of the neighborhood and the Vatican. Wonderful place to stay!
