Great location between Largo di Torre Argentina and the Pantheon.
It felt plenty spacious and elegant. There is a living area, dining area, and kitchenette downstairs. Lofted above the dinning area is the bed and bathroom. Bed was very comfortable. Air conditioning and wifi worked decently.
There was no large "chore list" for checkout, which weary travelers like me appreciated.
Although the was located on a smaller street that was less busy, the street noise at night could still be an annoyance. However, that may be ubiquitous for the area. You can hear people socializing on the streets until about 4:30 AM, but it mostly wasn't loud enough to prevent sleep.
The friendly host greeted us when we arrived and showed us the place and gave us some tourism pointers.
