Fabio's apartment is a perfect place from which to base your Rome travels. It is in an incredible location. The Vatican is a five minute walk (if that). I went to Mass there and then returned every day of my trip for at least a few minutes. You can also walk to many of the main sites in Rome within an hour. One day I walked down to the Baths of Caracalla (which is pretty far south in the city compared to where most people spend their time) and it took no more than 55 minutes. Fabio is also very helpful. He gave some really good food recommendations. He even let me keep my bags in his apartment after checkout until my train departed. My one complaint is he arrived 10 minutes after he said he would to allow me to get my bags. I had to run to the train station to catch my train. This was a little frustrating, but everything else was fantastic.
