Eleonora´s apartment is by far one of the best AirBnB I have stayed. It is in a quiet dead-end street but very close (walking distance) to the Trastevere on one end, Vatican City on the other and the historical centre across the river (Pantheon, Piazza Navona, Forum). The location could not be any better.
Inside the apartment, Eleonora has thought on every single detail far beyond what you would normally expect on an AIRBNB: coffee, tea, biscotti, as well as fully equipped kitchen. I specially appreciated she left oil, vinegar, detergent, and anything you may need for cooking, seasoning, or cleaning.
The apartment is small but it has a street view with windows to let light and air in. Just watch out for your head at the upper level if you are tall when you get up from the bed.
I highly recommend this apartment. You will certainly enjoy it.
