Great stay, we would stay here again. Very friendly host who was there to greet us and say goodbye. Good AC which you control and very clean. Very nice bathroom. Perfect place to stay for a few days.
The home is literally across the street from the Vatican, but far (45-60mn walk) from the other monuments (Pantheon, Colosseum, etc.) and the city center. There is a bus and train system, but the Rome bus system is more difficult and less reliable than other EU cities.
Overall a great place (besides the walking).
