When our bus from Siena to Rome, was delayed, we informed Lorenzo right away of the later check in. He waited for over an hour and a half and even way past midnight to make sure we got to his place and were settled in. He was also nice (not impatient at all) when we arrived. We were grateful especially as we were very exhausted and had been traveling with our big luggages.
His house is a 4-5 min walk to the train station and is 11 mins from the Vatican. Very convenient. The unit itself is clean and comfortable.
I also appreciate his tips and his answer in my questions regarding transportation.
We recommend booking with him.
