We have stayed at three different airbnb apartments in Rome in the last five years, and Carmen's apartment is our top pick. Above and beyond the obvious features that you can see for yourself (e.g., perfect location, great value, two bathrooms, etc.), everything the other reviewers have said is true: It is immaculately clean, everything is in perfect working order (e.g., two functioning AC units, beautiful bathrooms with endless hot water, great water pressure, and no flooding issues, as can be common in Italy), a really spacious interior, and a fantastic host who responds within minutes for anything you need--an early check in, booking a ride to the airport, etc. If you want to stay in the Centro Storico (historic center) of Rome and have all the creature comforts of a first-rate apartment in the U.S., this is the place.
