Andrea's flat is very well located, next to the public transportation and a short walking to the Colosseum and some central attractions, around 20 minutes as he describes.
The room is spacious, well ventilated, but as the window is to the street, a little noisy if you let it open. The flat wasn't so clean.
Andrea is very kind and friendly, we even went have cannolo one day and pizza another one. Very nice person.
