The flat is great, Lorenzo (and his mother) are great hosts .. he is very pleasant to chat with and would always give you good advice. We stayed for 5 days and met him twice but one feels like he's someone you know for a while. He's straightforward, chilled and prompt in his replays. The flat is about half an hour from major attractions and gives you a very good feel of Roman residential life style away from the noise of tourists, but still easy to get around.
