We stay in Air bnb homes all over Europe. This has been our favorite! This is because Sarah is so kind and thoughtful. She arranged a car for our airport pick up. She left essentials in the fridge for our breakfasts (eggs, bread, jam, butter, juice, cheese, etc..). She was extremely responsive to messages before and during our stay. She made everything so easy!
As for the apartment.. beds are comfortable. Nice shower. Washer and dryer. Kitchen has everything you could need. The location is walkable to the Vatican and close to public transit for everything else. Highly recommend this place.
