We stayed at Alessia's place for three nights and thoroughly enjoyed it! This is a very central location: less than 10 minutes walk to the main train station and 25 minutes walk to the Ferry port to the Capri island. It's also close to many eateries, including the most famous pizzeria in Napoli!
Alessia stocked up her place with many nice touches, including a welcome pastry box and wine/sparkling water in the fridge. We felt truly welcomed in her place. She is also quite accommodating with respect to check-in/out and provided useful local information. The communication is always lightning fast.
All in all, one of the best experiences I've had with Airbnb. We recommend Alessia and her place without reservation!
