my 11yo daughter and i stayed at Susy's apartment for 3 nights. It is a fab apartment in a wonderful location. It is really spacious and comfortable and some basic breakfast supplies were provided which is great. It is located right in the historic centre near all the restaurants, bars and museums, however, because it is up a side road it is pretty quiet. We couldnt hear any street noise, just aeroplanes occassionally (i think everywhere in the centre you can hear the planes as the airport is not far from the city centre). the aprtment has aircon which was appreciated as it was really hot during our stay. we loved the underground city museum which is really near.
We were out early one morning which was fascinating to see the fush stalls and locals doing their shopping before all the tourists come out.
Naples is hot and bustling and chaotic with scooters whizzing through the nartow streets and we were totally charmed.
