Very convenient location - walking distance to the Colosseum, Roman Forum and Metro station, lots of restaurants, and grocery store/convenience stores nearby. Apartment is secure and has an street side locked door, plus solid locking apartment door.
Apartment is spacious enough to fit 5-6 people comfortablely, but it has a few quirks - many electrical outlets did not work, and A/C units are only located in the two bedrooms and do not cool the living room (aka 3rd bedroom), kitchen, or bathrooms. Gas stove in the kitchen requires a cigarette lighter (provided by host) to start. 2nd bedroom and living room (3rd bedroom) face backside street which has many loud restaurants (often loud music) especially between 9pm-12am every night (weekdays and weekends) - the windows do not block out much of the sound making isn't difficult to sleep.
Minimal paper goods, and other toiletries provided - will need to purchase additional if staying more than 1 or 2 nights
Overall I would stay here again, but I would bring earplugs and plan ahead for toiletries
