Very nice apartment and very central. We were a family of 7 (4 adults and 3 children - ages 11,15 and 15). The apartment was spacious and a really good base.
It is very easy to find from Termini station and also very easy to access major attractions, nearly all on foot.
Natalia was a great host and arranged for our minibus back to the airport.
All in all a very good experience.
