We had a wonderfull time at the appartement. It was very spacious with a big kitchen and a nice sitting area with couch and tv. The house has blinds to block the sun and even when it does get hot inside each bedroom has an buid in airco which works perfect. The most special feature is the overview of parts of the city and the Vusivius from the balcony. We took the bus everyday though to go downtown, because it is 20 min to walk. It is advisable to check the timetables before coming to Napoli because most of the bus stops has none.
It lies on the path of landing and departing airplanes, but only a few come by every hour so it didn't bother me. Besides the planes only fly at day time.
So great apartment for your the price.
