We recently spent 8 days in Ostia and we really enjoyed our time at Barbara's place. The little appartment is equipped with everything and the beds and the shower (things we are quite picky about) were really good. Even the extendable sofa, which usually feels unconfortable for heavy adults, proved to be able to deliver a good night of sleep.
Communucation with the host went reaaly smooth. She was always punctual with check-in/check-out and promptly replied to all our enquiries.
We go to Ostia on a regular basis and we hope to have again the chance to stay in Barbara's property.
