Main positive thing with the house is the very convenient and secured parking for the car.
The tram station is very close, as well as all commodities (supermarket, pharmacy, fuel station, etc...). 15 minutes tram to go to Rome central station, it is very good.
The black point of the house is really the noise, due to tram line and road. If you are sensitive to noisy conditions, think about your ears plugs if you want to have a chance to sleep couple of hours.
The kitchen is also a bit small, with a lack of space to store stuff and lack of equipment. Fridge should also probably be replaced...
Bedrooms are big and clean, bedding is good.
Leonardo is a nice host, providing good recommendations for restaurants and being helpful and flexible for check-in and check-out.
