This listing is close to the Ostia Antica train station (not too difficult to find from the airport for a FIRST time visitor to Italy). The listing is also very close to a couple restuarants with very good food. If you are interested in ruins, Ostia Antica it's self is very close by.
Paola is a wonderful host who speaks English well. Despite my children arriving to the listing from the airport after 2:00AM (27 Euros), Paola was a very gracious hostess who was always available to assist us and to educate my children (21 and 25 years old) and I about any subject we were interested in learning about (directions to local customs).
I highly recommend this listing if you want to see Ostia Antica, be fairly close to the airport (27 Euro taxi ride vs 48 Euro taxi to center of Rome), and have a host who is happy to help and make your trip (whether it's your first or 100th trip) to Italy an enjoyable experience.
