We were looking for one nights stay somewhere near the airport, and that is exactly what we got. Patrizia was kind enough to fetch us from the local train station, and drop us off at the airport (note: the airport commute with Patrizia was cheaper than other local travel options, and very effective).
Very kind and generous host!
Strongly recommend this AirBnB if you are interested in visiting the local archaeological sites, and the beach (which is quite close ~15min train ride).
Otherwise, in terms of travel to central Roma, you can expect it can take up to 1hr to get to Termini station (15min walk to the local train station, potentially 15min wait for next train, 25min ride from Ostia Antica to Basiclica S. Paolo, transfer to the B line, and travel 11mins to Termini).
