Just had a fantastic week in Rome as a couple. Concetta and Giorgio are wonderful and accommodating hosts. They were a pleasure to deal with, quick to respond via email, answered all questions about the apartment and Rome in general. We found the apartment priced well and anyone considering it should factor in cost of public transport (1.5 euro/trip). You will most likely need it to reach the historical center. There are several bus options and metro stop 10-15 mins away. Take time to understand the bus system, it can be more convenient than metro for some locations.
Bedroom is large and is on the third floor of a building facing a busy street. We were not at all bothered by the outside noise. The only inconvenient item is the size of shower cabin. It is small - to reach something on the floor, squatting is the only option, no room for bending over (I am 6ft tall). There was an issue with hot water in the kitchen, Giorgio promptly offered to come over and look, but it was not enough of a bother for us.

Overall it is a great choice for anyone looking to stay outside city center in quiet residential neighborhood with all the conveniences.
