We had a great stay in Lido di Ostia. The flat was clean, comfortable and very spacious - perfect for a couple or even a small family. Also the location of the Airbnb is more than good, since it is just a few meters away from the sea and the promenade Pontile di Ostia. There a lot of Stabilimento/Beach Clubs nearby and if you prefer public beaches, you'll find some if you walk a little bit northwards or you can take a bus to the south. The bus station "Marina" is very close and it's also just a few minutes walk to the main station, from where you can go to Rome by train quite quick and easily.
You can find anything you need just a few meters or minutes away - a cute little cafe for breakfast (who also have non dairy/vegan stuff), a kiosk, a bistro/bakery (where you can buy very delicious and reasonable fresh pizza and bread, also for take away), an amazing gelateria (with tons of dairy free and vegan options), a big 24 hours supermarket, a drugstore, fashion shops and lots of restaurants and pubs.
We felt very safe in the house, as well as on the street.
The neighbours were also friendly and helpful.
Just be aware of mosquitos and don't forget to close the windows in the evening during summer for that reason.
Also a big Thank You to Barbara's Co-Host Ishari for the warm welcome and showing us the flat!
We would definitively stay here again!
