The place is very clean and the small touches, such as towels and soaps being provided, was much appreciated. It is centrally located, very close to the Termini (the main metro station) and 15 minute walk to the Colosseum. The neighbourhood may appear slightly run-down but we never had any issues and I would say it's quite safe and quiet at night.
We would highly recommend the Fassi Gelato place which is nearby (about 10 minutes walk).
Would recommend!
