Ambrogio's place is a great location to start your everyday explorations of Rome.
You can walk basically everywhere and can skip the bus rides which are generally unpleasant.
The apartment is clean and cozy and the beds are very comfy. Even the futon which is more like a real mattress.
The bed is in the back of the apt and and it's very quiet there.
The futon and couch are located at the front with a window to the pedestrian area which can get a bit more noisy. That said I still had very restful nights there.
Ambrogio himself is a very kind and friendly guy who will help you with any problems you might have.
Also he has a lengthy list of good restaurants etc at the ready!
All in all we enjoyed our stay a lot and I'm sure you will too.
