Its a beautiful flat. Big and spacious and very well appointed with all needs covered. Marina has incredibly high standards, so everything was spotless, fresh towels in sealed bags, the attention to detail was impressive.
Its very close to the central train station, so is right in the thick of things, flea markets operate daily around the flat.
I wouldnt bring my kids to this location, but as a lone adult I was fine. Youre in the heart of Naples after all!
