The apartment was perfect for two couples to share. It was very clean and neat. We each had a private room and shared a nice bathroom with big shower. Kitchen was well equipt with everything we needed.
Silvia went out of her way to make us feel welcome, she left some goodies in the kitchen for us and had extra guide books and maps about Rome. She also provided recommendations for good restaurants, shopping locations etc. Location was very practical, close to metro and bus routes, plus walking distance to Termini.
If you are a light sleeper, the road outside can get a bit noisy at night, but would certainly recommend it.
