First, to get them out of the way, the negatives, and there is only one: There were cleanliness issues throughout. The flat and its accoutrements simply weren't in a condition you'd expect when staying as a paying guest. It made our stay less comfortable than it could have been and required more of our time than reasonable to make it comfortable. That said, Roberta and Giulio seem like very nice people. Communication was excellent, and a small issue we had with the TV was fixed directly. The location is also excellent. Easy access to metro stations on 2 different lines, to multiple bus stops, and to the tram. Grocery stores, many restaurants, tabacchi (for bus tickets), etc. From the balcony, you can see Collo Oppio; from the front door, the Arch of Constantine on one end of the street and Quattro Coronati on the other. It's a very lively neighborhood. In fact, very noisy with lots of car traffic. Then again, it's the middle of Rome, which is indescribably beautiful. What a city. Tip: eat at Il Bocconcino. Really nice food, even nicer staff, fair prices.
