If you land on the airport Ciampino and you want to visit Rome, this is a great Airbnb to do so (especially if you have a rental car).
The appartment is a 10 minute drive from the airport, hidden away behind the restaurant Paradiso Terrestre which is owned by her and her brother. It offers a private parking space in front of it. Inside you'll find a kitchen (4*6 meters), bed room of the same size and a bathroom. Plenty of space for two. The apartment also features air-conditioning in both rooms. The host was very helpful and even gifted us a bottle of wine.
A Lidl is within 3 minutes of driving. A bus station is within walking distance and a train station (Capannelle) with free parking within 5 minute drive. This allows you to arrive at Roma Termini in 8 minutes by train for 1€ per ticket (order tickets online at trenitalia).
The only negative I have found with the location is that it's close to the airport so you'll hear a plane once in a while. But this is a small issue since you'll have your windows closed anyway to enjoy the air-conditioning.
