Dario gave me a very clear instruction on where to meet, and responded to all my questions within a couple of hours. His place is near Universita station, 2 min on foot, and he welcomed me with Napolitano espress and showed around the house. Not only that, he recommended great places to see and helped me book a taxi.
His place is clean, cozy and is much better in reality.
I had a wonderful time at his place and would definitely stay here if I get to visit Naples again
