The apartment is great. The area of Piazza Bologna for me is the best part of staying at Jessica's apartment as the area is very convenient in terms of public transportation and stores, supermarkets, restaurants and bars/cafes. Piazza Bologna is one of the metro stops on linea B and is close to both Stazione Termini and Stazione Tiburtina, two of the main train stations in Rome that will take you everywhere in Italy and in Rome (including Fiumicino). The apartment is clean and nicely remodeled with updated kitchen, modern and new furniture, a redone bathroom and a comfortable bed.
The two things I would point are to anyone considering renting the place is first, if you are limited on mobility or have difficulty with stairs, it might not be the best choice. The apartment is on the third floor (US)/second floor (Italy) and the elevator doesn't stop on the floor. So you have to take the stairs. The stairs (as the elevator) are very narrow so it can be challenging to go up and down at least with larger pieces of luggage (and heavy ones).
Second, if you are a light sleeper, the apartment might not be the best choice at least during the summer months if you like to sleep with the windows open, as I do. The street below is a popular meeting point for either university students or just young people in the neighborhood, and they were outside talking, laughing and hanging out until late at night. Jessica has new windows which keep out the noise when closed tight and also air conditioners in both the bedroom and the living room, which is an easy solution to the problem, if you prefer sleeping with the air on and thus not having to listen to the voices below.
