Pros:
Location: absolutely brilliant - everything is near: the sea, the pleasant streets of Ostia Lido, bus to airport and even Rome
House: nice and new
Apartment:
very peaceful, silent and clean
Cons:
The balcony was very nice but there is never sun, as it faces to backyard
The shower was too small (I quess this is normal in Italy)
The apartment was nice but compared to other airbnb-apartments where we have stayed, it was very simple and basic.
