Excellent location! You cannot ask for a better location. Close to the Pantheon, Trevi Fountain and Piazza Navona, and right next to a 150 flavors Gelato shop (yum!).
Excellent and professional hosts! Beautiful apartment. Very clean. Flavia and her mother were very willing to help us with anything. They made us feel welcome. They provided us with umbrellas for the rain, and fruit when I asked where I could buy some. (Flavia's mom brought us cold fruit in a bowl). There is a small refrigerator in the room that had drinks for us; pastries for breakfast were provided. Both ladies are gracious and beautiful like their home.
Overall I would rate our stay 5 stars all around! You would be very lucky to find the apartment available for your stay.
