This is a good apartment in an excellent location. We you step out I to a small square, it feels like you are in the heart of Rome. Only one street over is Piazza Novona that is humibg through the day and night.
My one recommendation for light sleepers is to bring some ear plugs the apartment has great shutters but is only one floor up from the street. It can be a little loud on a Sat night. It was no problems for me when I wore ear plugs. This will be the same for nearly any apartment near the heart of the city and an understandable side effect of this apartments great location.
PS: The apartment feels secure with two sets of very sturdy double doors.
Also, Alex the host was very accommodating and understanding of my requests. Highly recommend to any I s wanting to experience Rome.
