The apartment is in a great spot, two blocks away from world's best pizza place (Gino Sorbillo, thanks to Nicola for recommending it) and less than 15 mins walk from L'Antica Pizzeria da Michele (very first pizzeria in the world). Apartment was nice, clean and very spacious compared to other Airbnbs I stayed in Italy.
Nicola is a great host. He also helped us with finding a cab to the train station from his apartment. I recommend it.
