The best host.
the room is really near the metro station, bus station and alibus. And I mean really close.
the room is new, with fair internet, good AC, hot water, good bed and is really clean.
It is in the third floor, but there is an elevator (0.20€) each ride, but the host gives you a key for it.
there's only one problem, Garibaldi place. Did not have any stress there, but it can be dangerous at night. keep this in mind if you are going to Naples alone and will be walking alone at night.
during the day there are a lot of people, movement and it is safe.
