My cousins and I had a great stay at Stefano's apartment.
It was clean and had all the basic amenities that a city traveller needs. The apartment is just a 10 minute walk to the Vatican city entrance and there are plenty of good restaurants, bakeries nearby.
Stefano was very gracious and showed us the best sights to go to on our 3 day stay. Most great sights are within a 6KM radius, which is pleasant for such a short stay. Thanks Stefano!
