Prior to our holiday, I had been in touch with Alessandra to ask a number of questions. She was very helpful in providing info on location, available tour guides and transportation to/from the airport.
Upon arrival to the apartment, we met with Alberto who gave us the keys and walked us through some house-keeping rules. The apartment was lovely, clean and spacious (for 2 people) and the location was spot on. We stayed in Rome for 4 nights and didn't take public transportation once - all the major sites were within walking distance (if you enjoy seeing everything by foot!).
The only downside was the noise levels in the bedroom. We were on the first floor facing the main street. Having said that, we got use to it, especially after a couple of drinks!
Overall, lovely stay.
