Silvano's sister welcomed us at the Ostiense railway station, and walked with us to her apartment, in a residential neighbourhood. The apartment is very clean and our room was very cosy. Rome isn't a big city and subway or tram takes under 10 minutes to the city center, on foot 30 minutes. We stayed two nights. Perfect location for those arriving at the airport late and leaving early (like we did), because the nearby airport train only takes 30 minutes from Ostiense to Fiumicino airport. One of my best experiences with AirBnb.
