Stayed here in late January with my Parents. I would highly recommend it to anyone.
Pros:
-- Amazing Location right behind the Pantheon. Within 15 -20 mins walk to all attractions
-- Extremely clean
-- Spacious and design was well thought out
-- Nice and warm in the winter with heating board in every room
-- Host made an exception for early check in and waited for my parents when they got lost.
Cons (non of them are deal breakers)
-- Main bedroom was very comfortable but the sofa beds in the living room weren't so much. It is a sofa bed so it is as good as it gets
-- It is on the second floor near a main attraction with double layered windows. But if you are unlucky at night, you will still be able to hear garbage trunks and drunken people passing by.
-- Second floor, no elevator. (Typical in the historical city center)
