We had a great stay at Federica's apartment!
Nice quiet and peaceful neighborhood near sea (5 mins by feet).
It is very close to bus stop (Corso Duca Genova- Repubbliche Marinare, bus #1). From there it is about 10 minutes to Lido di Ostia (Lido Centro) Train Station, that is very easy to reach from Rome (only 1,50€ trainride, 20 Minutes).
The apartment with balcony and view to the sea is modern, very well furnished and was equipped with all things we needed (inclusive washing machine).
Federica's husband gave us detailed locations & descriptions about bars, restaurants & shops in Ostia. He was also available and responsive to every our question or request we had during our stay (we were given the internet access with limited traffic, so we had to reload it once).
There is the supermarket (panorama) and marketplace nearby where you can find fresh vegetables and other italian food.
All in all we would definitely recommend Federica's apartment especially during summer time!
