The apartment is in a really lively bit of Naples, with a great view. The outside is a bit scary if you've never been to Naples (like me) but the area is actually very good. Naples is just a bit "lived in".
Handy for lots of shops and restaurants and for the hop on hop off City Tour Bus. This has two routes both of which you can get from the nearby castle.
Apartment was well fitted out and clean. Would stay there again if back in Naples.
