First of all, we really like the apartment. It's well equipped and everything is new and clean. Giovanni and his family has been keeping everything tidy all the time. At first we did not meet Giovanni himself but his mother was very helpful. Though she can't speak English, she is a funny and lovely lady and showed us around the house. The heating went down for a while but was quickly fixed by Giovanni. The location may not be the most perfect but all and all very comfortable experience at Giovanni's.
For those who come to Naples for the first time, I would recommend this place.
