We were disappointed by this rental.
Location: While it is very close to the Trevi Fountain and Pantheon, it is far from any semblance of "normal" Roman life. The street on which it is located is filled with souvenir shops and tourist-trap restaurants. However, the courtyard (and turtles!) were indeed a real highlight for the kids.
Apartment: It is very small and the comfort/design was far from what we expected, given the price. Only a door separates the apartment from the rental next door, so that it is possible to hear everything and there is little privacy. The beds, blankets and pillows are old/low-quality.
Cleanliness: The apartment should have been cleaner at check-in. The toilet was dirty and there were hair/dustbunnies in the corners.
We were traveling with relatives, who stayed in other Airbnbs (same price, better location, much higher quality rentals). Therefore, I can unfortunately not recommend this rental.
