Lorezno and his mother are very nice and helpful people.
Flat is situated near (15 min on foot) the train station (5 min to the seaside and 20 min to Rome by train). Ostia Antica is very good place to stay - few shops, restaurants and huge archeological area to visit.
Everything we needed was provided: towels, hair drayer, kettle with tea&coffee, nice breakfast everyday. We are very happy about this accomodation!
