This is possibly one of the best places to experience life as a Neapolitan. I felt as though I was in a Sophia Loren movie set when I stood on the balcony (which is four floors up) and looked along at the lines of washing and listened to the cacophony of music, motor scooters, chattering and noise. It is really central - just off Via Toledo, close to the port - you HAVE to get the ferry to Procida - and it’s close to many other landmarks. There are plenty of great eating places really close by.
The flat was exactly as described, so no disappointments there.
Naples is a vibrant, noisy and exciting place to be, I couldn’t think of a better place to experience it.
