If, like myself and my wife, you're looking for an authentic stay in Naples, stay here.
We were checked in by Marinas husband at 3pm (1 hour earlier than we had paid for because our flight was early and they didn't want us to have to wait).
Rosario was lovely and grew up in Pompeii so knows the area well. Marina and Rosario have put together a booklet of both the tourist "must sees" but also hidden gems only locals would know about.
There is a reason these guys have a huge amount of positive reviews. Could not recommend them more.
