Had a fairly good stay with Cinzia. The apartment is in a pretty good location near the Vatican and more importantly near public transit lines and grocery stores. Cinzia also provides many extra amenities so I never felt like I was missing something, like an extra towel, during my stay.

There are some minor things to caution people however before booking.
1) WIFI is very average. I stayed at the apartment with two people and we definitely felt like at times the WIFI slowed down to the point where neither of us could use it.
2) Hot water machine is very small. Two people cannot take showers one after the other, you have to have them wait.
3) While not extremely noisy, light sleepers will definitely hear the mornings commuters in the morning as the apartment is near the staircase.
4) Bathroom usage is definitely for 1 person at a time.

I overall had a good stay with Cinzia but would at least take a moment to consider other listings in Rome before booking again. Maybe the listing is perfect for one person but for two found it on the small side.
