Nicola and Antonella are fantastic hosts. And not just great hosts but truly wonderful people. If you speak good Italian, it's well worth sitting down for a chat. (Nicola speaks reasonably good English too). We have rented dozens of airbnb's and they rate right at the top as hosts.
We loved the apartment. Roomy and nicely appointed. Nice terrace. Unusually well stocked kitchen. Great neighborhood. Easy access to metro. (Tip: the ticket machines at the nearby Piazza Amedeo stop weren't working well for anyone, but you can buy a day pass from the cashier at the Metro Bar just outside the tunnel.)
A first rate experience overall.
