For location and charm, you cannot do better than this apartment. Large, airy, with a wonderful terrace we enjoyed immensely. (There is even a grocery store on the ground floor of the building, hard to beat that for convenience).
The Trevi Fountain is just around the corner and there are so many cafes it was hard to choose.
When we did run into a maintenance problem, it was quickly corrected.
Highly recommend if you'd like to feel (if only for a few days), you are part of the neighborhood.
