The apartment is tiny but nice and adequate for my parents and I who stayed there for 3 nights. The location of the place is central to most of the attractions except for the Vatican City. It is also conveniently located near to a supermarket (2-3mins walk). If arriving by train, the train station is only 15 mins walk away.
My only issue is that if you are a light-sleeper, you will hear the random sirens from the fire trucks responding to emergencies. Other than that, it’s a nice place to stay for a short holiday when exploring Rome.
