David and his wife are the kindest host you can wish for. They went out of their way to recommend us good beaches and restaurants (which turned out to be amazing) and made sure we were enjoying our stay.
The room is as shown in the listing, not huge but very comfortable and clean. The balcony is lovely for breakfast or dinner with even a bit of a sea view, and it was extremely nice to find the fridge stacked with basic necessities if you get hungry before your first trip to the supermarket.
We can easily and without reservation recommend this place to people looking for accommodation in Ostia and we will certainly be back if we ever find ourselves in Rome again!
