We stayed for 5 nights in October 2014. The room was very clean, comfortable and Letizia was very helpful. We loved the small kitchenette where we could make a cup of coffee or tea before getting out.
The location is close to the vatican and metro, although we only used taxi's.
We had breakfast (included in the room prise) in the 'Luma' bar just outside the door. We really loved this place, good coffee and cappuccino.

Highly recommended!
