Overall - the apartment was amazing. Large, very nicely arranged and well equipped. For an apartment in Rome it was also very bright - there was 1 large window in each room. What I want to emphasize - a bathroom with a jacuzzi is like a second apartment, I really don't exaggerate, you can live there. Also the beds were very comfortable.
Location - great! Still close everywhere (but I like walking!), but a place wasn't "trampled" by toursits. It was also quiet. However n the immediate vicinity of the apartment I didn't see any bigger shop (but also I didn't need it so I didn't look it a few streets away).
The host - very flexible, there was also no problem with quick communication.
Disadvantages
1) Occasional problems with water pressure, even if the boiler is fine. However I'm not sure if it's a problem with the apartment or with this part of the district, as I had the same problem in another apartment 2 streets away.
2) Few plates, glasses or cups - if you are in 2, all this will be enough, probably for 4 people you will have to wash the dishes after each meal.
3) If you want a nice view from the window, this is not the apartment for you :) (I didn't care, the most important thing was that there were big windows in every room).
