Maurizio is a very pleasant host. He is reactive, extremely nice, gives you many tips on where to eat, what to visit... and is discreet, while at the same time willing to help you as soon as needed. Just for the human part, I had a great stay.
More than that, the apartment is very central in Napoli, has all the equipment needed (Maurizio even offers the breakfast), and, which is THE best part: an AMAZING view. The pictures don't lie, and I won't either: I went there every morning and every night for a few minutes just to enjoy the moment, before and after my strolls.
So thanks a lot Maurizio ! I'll come back here :)
