Beautiful studio in great location.
Near the Piazza Dei Fiore, but far enough to be quiet at night, with decent grocery and wonderful bakery and brewery (!) and good restaurants and wine bar nearby, at better prices than some other places.
Walking distance to most tourist sites; Andriana helped us get cabs when we could not walk.
The apartment decor made us know we were definitely not at home, and shutters closed out the street lights. AC was fantastic after a few hours in the hottest Roman summer in history.
Only shortcomings would be that refrigerator is very small, no kitchen sink, and taxi stand is a bit of a walk when it is hot, and the bell tower is off by 12 minutes, so not reliable for scheduling departure!
Andriana was extremely helpful - more than most hosts.
