I had 2 perfect days in Piera's apartment. She is a really great host, always ready for a chat and to involve you. I've chosen her apartment because it is literally in the heart of the city. I personally think there is no better position from which to explore the wonders of Naples. In the apartment there is everything you need and more, it is very clean and well furnitured. The rooms don't have windows, but this isn't rare for apartments in the old town.
