My boyfriend and I stayed at Valentina's house a few days near new year's eve. Valentina and her family were really nice. They are kind, educated and nice people, which immediately made us feel at home.
The room was clean and bright, exactly as described as well the private bathroom. We were able to use the kitchen. A plus was the cat and the dog that made the visit much more special and cozy. We definitely recommend staying with them.
Public transport is very good, with the bus in 15 minutes you are in Roma Termini. However, if you prefer the metro there is a metro station not far. There are several supermarkets, bars, bakeries and restaurants nearby, in fact, we fell in love with a Chinese restaurant that Valentina recommended to us and we have to return shortly.
