Great host I've ever seen so far.
Starting from the beginning of our Rome trip he helped us all the time. He got us from the train station, he explained details about Rome and the perimeter that we stay, he advised us good places to eat/drink.
The apartment is also very nice and clean. Everything we need is in the house when we go there.
Do not hesitate to stay in Fabrizio's apartment. You won't regret.
