I have stayed before in that area. It is centrally located and all sights are in walking distance (2km) with the Trevi fountain a couple of meters of walk.
I really appreciated the bathroom amenities. It makes life so much easier and the quality was good.
Also the basic needs were provided, paper towels, napkins, salt, pepper, olive oil, coffee, tea, … so nice that you do not have to run out and buy those too.
With my 2 year old it was a comfy place to stay.
Rafaella was always reachable and arranged our transfer.

The only thing I misunderstood was that the terrace is not reachable through the apartment. So, I couldn’t leave my sleeping daughter in the apartment to go up.
