It was clean, very spacious, nice comfortable furnishings. We had no problems with heating, hot water or electricity (always a consideration in these older renovated buildings). The location is excellent, short walking distance to grocery stores, restaurants, etc.
During the day there is some outside noise from street traffic, but at night it was very quiet and never a problem for us. We did have internet connectivity issues, but I'm confident the host will resolve this with her service provider.
We spent one week here, and would book the place again if we revisit Rome. The host and her assistants always responded promptly and courteously to our messages/calls.
