This apartment is a great central location to explore all of Rome. It's about a 20-minute walking distance to all of the sights and accessible to major bus routes, making it an ideal location to explore multiple areas of the city.
The apartment is not on a main thoroughfare, so the primary noise you will hear is from scooters / motorcycles driving through the small alleyway (same as everywhere in Rome). There are several great restaurants and grocery stores within 5 minutes of the place, so you never have to worry about finding food. Outside noise starts to dissipate by midnight, but it can be troublesome if you are a light sleeper.
The place itself has everything you need: basic kitchen amenities, functional toilet and bidet, and nice cold air conditioning. The walk-in shower is huge, warm, and refreshing. The only bathroom is through the main bedroom, so if someone is sleeping on the sleeper sofa be aware that they may wake you to walk through.
Antonello is a great, responsive host and my family and I would stay in this place again in a heartbeat.
