There were 4 of us that stayed in the flat for a week. The flat was as described in the pictures and was very clean. Dania met us for check in and gave us information about the flat and area. She was very friendly.
The location was also excellent as we could walk to the main attractions. If you prefer not to walk then Cavour metro is only 3 minutes away. There were also good gelato and food places very close.
The only tip I would say is to be careful with the hot water if there are lots of people showering one after the other the hot water can run out and take a while to heat up. There were 4 of us so I think it was down to this. I do not think it would be an issue with less people.
However we found it was not an issue once we were careful with the hot water and left gaps between showers.
Overall it is a great place to stay if you are in Rome and we would stay again.
