The flat is spacious, and in a great location. We walked from there all the way to the Coliseum and the circus, for example. But if you prefer, a train station that take you direct to Termini is a 3 minutes from the flat. And of course Uber!
The main feature of the flat is the incredible view over St Peter - can't beat that!
But be prepared to have to go to the supermarket upon arrival, as you will find an empty fridge and kitchen - the owner prefer to clear everything - bizarre, but that how it is.
A very enjoyable stay!
