Chiara is a wonderful host, who has done perfect service to let us have a great time.
The appartment was exactly as described.
Location was perfect with a subway station at the door (although we did nearly everything walking, Collosseum is in ~20min walking distance, historical center 40min, a nice market on the other side of the street, and several nice restaurants in viewing distance).
And Chiara improved our stay with several great tips.
