Robert's place is awesome. The room is very large, air conditioned and clean. It can easily accommodate 2 couples or a small family - I don't know if he allows for this but...I'm just saying. The view of the Napoli Bay from the balcony is very nice.
There is a sushi restaurant just down stairs, bus stop across the street and the Harbor, beach, city center and train station(s) are not far away.
You could not ask for a better and more charming host than Roberto.
His place is highly recommended- I will stay at Roberto's place whether I'm back for business or pleasure.
