Carmen's place is perfect if you need something near Termini. It is clean, comfortable, and private. The room is lovely and Carmen is very responsive. Her door has good locks, so the place is safe. However, I would avoid staying in the Termini neighborhood if possible. The neighborhood is covered in graffiti and the building Carmen lives in is full of drunk young people. If you need to stay near the train station, you should stay with Carmen. If you don't absolutely need to stay in this area, look elsewhere.
