The location does not get any more central than this. You can go anywhere from the "central" train station that is a few minutes walk away. The neighborhoods in walking distance present hundreds of cafes and restaurants with the best coffee and the best food. There are a lot of historic sites in walking distance as well.
The place itself was very tidy, clean, nicely prepared. There is a small fridge and kitchen counter with a small picnic stove if you want to boil something. You could, of course, cook something if you wanted, but come on, you are surrounded with arguably the best food on the planet so go out and enjoy!
Our host, Antonio, was AWESOME. He welcomed us to the place, he guided us on where to go, what to see, where to find good pizza! He was very helpful, not only about the place but also about anything we wanted to know for having a great time in Napoli. We confidently recommend Antonio as your host if you are coming to the city.
