Very nice place to stay. We were a family of 4 with teenagers and we fit perfectly. The apartment´s got averything you need and Clo will make things easier with her help. She was waiting us at the train station!
There is a 24h supermarket a block away and a train station (San Pietro) 5 mn walk away. There is no better location to get to the Vatican, specially on Sundays when the police control is on the Piazza and not on the access to the Basilic.
Should you want to go to some other places a nice 15 mn walk will take you to Metro, bus stops or to one of the hop on/hop off buses main stops. For instance, we took a taxi close to the Fontana de Trevi to the apartment and it was 14 euros the 4 of us.
We will definetely come back to Clo´s on our next visit to Rome
