Fantastico!! I stayed 36 nights.
Apartment:
Delightful, well-appointed with furniture and kitchen equipment for cooking, warm in the winter (due to the supplemental heaters), and easily accessible. Does have a lift, but also 22 stairs which are of normal depth, breadth, and incline, easily traversable. Internet was 80 down and stable for streaming and smart working.
The living room is on the street and so buses rumble the apartment when passing, but the bedroom is in the back with two doors that can be shut. For this reason, the bedroom is silent.
The bathroom, shower, and bed are all of a comfortable size and fully functional.
Location:
Superb! Rome has many fantastic neighborhoods, Piazza Barberini is one of them. Metro and many bus lines are within 200 feet. Trevi is 10 minutes, and grocery stores are 2 (Pam), 6 (COOP), and 15 (Conad) minutes walking distance.
Host:
The best! Superhost, indeed. Kind, courteous, and generous. Riccardo was attentive to continual maintenance of the flat as well as any need or question that I had. He runs a nice business. Thank you, Riccardo!
