The apartment is in a very busy location which made it very noisy - the traffic noise is continuous night and day. Obviously the owners cannot help the traffic but in order to get any sleep the windows have to be completely shut to cut out some of the noise which then makes the apartment very hot. There is no air conditioning which would have made it much more bearable. The kitchen facilities were poor..pans with no handles, knife with broken handle. Would be useful to have instructions on how things worked. We could not get washing machine to work at all. It did not wash or spin clothes.
On the plus side it was close to the metro which is easy to get around by and cheap. If you are happy to walk it is about 20 minute walk to centre of Naples and lots of restaurants.
