Maurizio was an excellent host. He provided clear instructions, responded very quickly, gave us some great recommendations and booked us a taxi to the airport.
The air bnb was safe and secure. It's only a 10/15 minute walk to the Vatican City and there are excellent transport routes to the centre.
I'd recommend Boris Cucina & Salotto as a restaurant to visit nearby. The food was lovely, staff were really friendly and the interior was very quirky.
