Functional apartment in a fabulous location for seeing the sights of Rome. We were able to walk to all the main sights, even with relatively young children.
Although it is on a busy square in the very centre of Rome and the traffic hardly stops, there was little noise in the apartment and it didn't bother us at all. Unfortunately there was more noise from the apartment next door, through the (locked) connecting door!
Giulia is a really responsive host and organised reasonably priced and reliable transfers to and from the airport.
