The place is wonderful, a real oasis, where you are woken up only by birds' twitter. The hosts are helpful and gracious. The huge garden, sprinkled with gazebos and Roman ruins, is incredible. The only price you have to pay is that it is not near the center, but a bus will take you to the metro station in 10 minutes. It is not near the center but it is in the middle of the beautiful archeological park of Appia Antica.
