Stayed there for two weeks as a family. Our experience was OK. Not that much great as you read in other comments. It is a studio separated from main apartment so you hear voices of the house owner time to time. Water heating is barely enough for two persons to get shower. Wi-Fi is not reliable because you've it via router from house owner.
House owner and her family was quite helpful. They tried to make it pleasant for us.
Price is little bit expensive tough it is a good option in Rome. I can recommend the place with some reservations.
