It's in an exceptionally quiet location, as the hotel is an 8-10 minute walk from nearest traffic light. No noise from parties, busses, crowds, clubs, cafes, etc, which is unusual for relatively central location.
The Colosseum is a 25-minute walk or 7 minute drive, and the Circo Massimo and Piramdie train stations are each about a 15 minute walk. The only occasional noise is from the shoe heels that click on the stone floor hallways and stairs.
The employees are very relaxed, hospitable, and attentive. The nearby shops in the area around Piazza Testaccio are filled with locals that seem a world away from the touristy areas.
