Andea was a very welcoming host, from our booking last September right up to the end of our stay yesterday (16.05.16). He helped us with directions from the airport and met us at the apartment.
The apartment is charming; small and simply furnished, and very clean. It is in a very characterful part of town with interesting distant views over rooftops. Breakfast on the balcony was a real treat. The apartment is on the fourth storey so be prepared for a climb!
Regarding situation, one can walk to the Vatican in about 20mins, and to Colosseum, Circo Massimo and Palatino in about 25 mins.
I would recommend this apartment ro anyone who desires a centrally situated, 'authentic' base.
