The apartment is located in a very central place, close to the most visited and busy walkway in Naples. It was very clean, with new furniture, showing that the hosts really care for the visitors. Egidio and Sonia also provided us with a binder with very useful information for the city. The only downside of the apartment was that it was on the 5th floor with no elevator, which can at times be tiring.
Overall I would definitely recommend it to a friend, and I would gladly visit it again in the future.
