We loved this beautiful apartment steps away from the Vatican but on a quiet little street (with no car traffic)! There are several restaurants, shops, and small markets dotted along the street of the apartment buildings.
We brought our 3 children including a baby and found it to be very child friendly. Marco provided a crib and we brought a small portable high chair.
The air conditioning worked very well! We turned it off while out touring and came home to a very cool apartment at the end of the day. Tile floors were beautiful.
Kitchen supplies were very helpful and adequate.
Note that the apartment is on the ground floor and if noise bothers you at night, you may prefer something on a higher floor. I used a white noise app on my phone and found that adequate.
I appreciated being able to bring the stroller and suitcases in on the ground level with just a few steps to the door of the apartment.
All was great!
