Great stay. Perfect location, walking distance to all major tourist points. Supermarket right on the next corner. The house is as described, spacious, well decorated and cozy, very convenient. We enjoyed a lot the 3 days journey on Carlo´s house. They were wainting for us on the main entrance, showed us all the facilities and gives a map a tips for enjoying our stay even more.
Check out was also great. He even let us keep our luggages within the apartment way after the check out time, so we could keep enjoying Rome during the last day.
The only con side is that the entrance to the main building was kind of smelly, but not all within the house.
Would repeat again.
