The apartment is a great place for a long weekend away. Centrally located and within walking distance of the metro, train, historic centre and also various good restaurants.
It is located near a church like other reviews have noted, this does mean that you can hear some quite loud bells going off. This was not really an issue though, as it is not all day and they usually go off in the mornings when you should be getting up and ready to explore all the lovely things in Naples and the surrounding area.
The apartment was very clean (much cleaner than most hotels I have stayed in), it is also well equipped with everything you need in the small kitchenette if you do decide to eat in (although who would with all the food Naples offers?!)
The host was very accommodating and friendly. They also gave us some great tips for local restaurants.
