Location, location, location!
Giovanni's apartment is in a brilliant location. The Colosseum, Forum etc are literally at the end of the street. Whilst the other main tourist places are all within easy walking distance- as are restaurants and shops. There is a small supermarket 5 mins walk if you are looking to cook for yourselves.
The flat is on the second floor - there is a small lift needed-and is clean and very comfortable. The street outside was quiet at night and the bed very comfortable so we slept well.
Giovanni sorted a taxi for the airport for us which was great. We went back via the colosseum metro station at the end of the street and the airport train from the main station - which was also very easy. So getting there by public transport from the airport should be easy. ( The ticket machines at the stations are easy to use)
Giovanni responded to our emails quickly and was very helpful.
We would highly recommend this place.
We had a great stay!
