We would recommend Rosa's place in Rome wholeheartedly.
Location was wonderful, just outside the colosseum, walking distance to Pantheon, Trevi fountain and Spanish steps, and so many Wonderful restaurants. Colosseo subway station is right near the house, making getting to her from the airport easy (it took about an hour to get to her place from the airport)
We felt safe and comfortable in her flat. it's on a quiet street but all the streets around hers are lively. The air-conditioning was heaven sent, given the oppressive heat in August. The bathroom itself is quite spacious, but the bath is a bit small. However it was clean.
Rosa was very communicative,and understanding. We would love to stay with her again!
