Firstly, I have to say Naples itself is not a very nice holiday destination. There is lots of graffiti, little to do and the locals are, in general, far less friendly than in other Italian cities.
The apartment is located down an intimidating alley off the main road.
Inside is much nicer. It is bigger than it appears in pictures and is clean and bright.
There is only air conditioning in the bedroom but it is very good.
The kitchen has a supply of pots, pans and plates. There's a microwave and a hob but no grill or oven.
