Federica's spot is maybe one of the most special AirBnB's I've ever stayed in. Being on the grounds of the castle in Ostia Antica is really something you won't feel until you get into the apartment and realize you look out onto the castle. We lucked out and happened to be in town during their historical reenactment weekend, which made it extra special. That said, the ruins at Ostia Antica are a ten minute walk away (and are absolutely worth visiting and seeing), there're a few restaurants in the town nearby, and of course the train can take you to Ostia Lido or Rome. Federica was even nice enough to arrange a cab for taking our party to the airport early in the morning. This place is going to stay with me in memory for quite some time.
