I've recently spent 4 nights at this apartment and can wholeheartedly say I've enjoyed spending my vacation there. The location is unbeatable, private transportation to and from the airport as well as check in and check out were super smooth and quick, communication with the host was fine as well.
As to the apartment itself: It's obvious attention has been made to its interior design as it doesn't look like an ordinary Airbnb apartment. Ample space for two (i.e. 2 bedrooms, 2 full showers and toilet), very very quiet at night and convenient for exploring Central Rome by foot.
Despite signs of increased wear and tear, lack of ample plates and cutlery, which I'm sure the host will take into consideration, I'm glad I stayed there and would certainly recommend it to others.
