Roberta's place is like a cute Roman mini-hotel, on the 5th floor of a building near Rome, Termini station. Roberta and the other host are very accomodating, communicative, and truly warm-hearted. The Air Conditioning is AMAZING and I recommend bringing ear plugs in case the trains bother you when sleeping. The local is in a safe part of Rome, near many restaurants and bars, and only 2 miles walk from the Colloseum. highly recommend.
