Our experience here was slightly atypical since Ilaria was not in present during our stay. Nevertheless, her husband and mother directly made us feel very welcome (and encouraged us to practice our Italian).
Communication was perfect, although it was hard for us to predict our arrival time. After arriving in Rome much earlier than expected, a few WhatsApp messages were sufficient to arrange the arrival.
The room was very clean and the flat as such is incredibly nice, especially given that it is in the middle of Rome.
The location of the airbnb, close to termini, is very convenient (both for parking the car and for train/metro connections). Just keep in mind that it is not the nicest and most romantic area in Rome (although such areas are within walking distance).

In short: a nice place to stay and to start exploring Rome.
