This place was great. We had already been sent an email with directions to the place by bus and metro, with specific instructions for cab drivers and a picture of the front door so we could find it if we missed finding the street number. Francesco wouldn't let us carry a single piece of luggage to our rooms. We found out he gave us a triple for the price of a double, because "you are staying for more than a few days and I wanted you to have more room". Breakfast was served to us in our room for the entire stay. When I said something to my wife about the strong coffee, the next day my coffee had more milk in it. When I mentioned that I like strong coffee (again to my wife, not to him, who I didn't even think was in earshot), the next day the coffee and milk were served in separate containers. He went into the attic to pull down one of the fans stored for the winter, because I had mentioned that I have trouble falling asleep without some kind of background noise in the room. When I asked Francesco whether there was a taxi strike (I had gotten an email saying our shuttle to the airport was canceled), he called a friend of his to drive us to the airport. He even offered to go with me to the supermarket across the street to help me find the best cheeses to try and take home. The hosts were so helpful and friendly that my wife friended them on FaceBook and we've invited them to our house the next time they visit the US.
The triple was spacious, and the double we stayed in later in the week was roomy enough (we spent a few days in Pompei, and they held our luggage until we came back). Both rooms were quiet, though you'd hear some background/moving around noises in the middle of the day (primarily because it was so quiet that you could hear minor sounds like footfalls and dishes being picked up). There was no need to bring soap or large towels as they often advise for trips to Rome. The location couldn't be beat; about a 10 minute walk from the Forum and Colosseum, and less than two blocks away from Via Nationale, lots of shopping and two major bus stops. There's a grocery store right across the street and 8 restaurants less than a block away. The breakfast nook has a shared refrigerator and microwave for dinner leftovers, and they have a wireless router for free wifi. There are at least 5 rooms on the ground floor, so we never climbed more than a few stairs.
If you have questions, you can contact the hosts; they're very good at responding to email. Very inexpensive by Rome standards (€80 a night, second week of March 2010), and we enjoyed our stay there much more than a higher-rated and brand new hotel we stayed in at Pompei for about the same price.
