We had a great time in Rome at Stefano's place but there were a few issues that stopped me giving it 5 stars. It certainly could have been cleaner - there were several used personal items from previous guests that should have been disposed of and we had to clean the pans, utensils, plates and cutlery before use. The kitchen was also missing a few basic everyday items like a kettle, toaster and wine glasses. The location is convenient for travel to & from FCO but it's not a great neighbourhood itself (although it's not far to walk to Testaccio or Trastevere) and there's a bit of noise from the road and from neighbouring apartments. Overall though we had a good stay and I'd definitely consider going back.
