Federica was a wonderful host. The room is spacious and has a little balcony. The house is located in a quiet non-touristy neighbourhood with very easy access to metro, bus and train stations. There is a supermarket just around the corner, and there are all kinds of shops and restaurants in the neighbourhood. Vatican City is within 10-15 minutes walking distance. You can also very easily walk to the historic part of town if you do not want to use public transport. I would definitely recommend staying here.
