Absolutely the best place I've stayed with airbnb)
If you want to have true Roman vacation this is the apartment you need to chose.
Location is very nice, not far from Piramida metro station and Ostia railway station (which you can reach directly from the airport).
Flat is clean, cosy and wonderfully decorated.
Sergio is a great host, unfortunately met him only in the morning when was already leaving. But he took care in advance about my arrival, gave me all necessary instructions how to reach the place. Highly recommended!
