Very nice location, lots of information on Naples and surroundings, close to sites, subway etc. Apartment is clean and well furbished. Small kitchen but then you don't need it. You should eat out ! Nice welcome by Gisella. Pleasant communication with her. She works nearby so is available should you need assistance. Gisella can also take care of transfer to airport or station. She seems to know the whole neigbourhood.
Appartment is technically speaking on first, but in practice on second floor, so some stairs need to be climbed. Some noise from neighbours in the beginning of the evening (all windows in Italy are open), but quiet at night - especially when compared to the streets around ! Internal steel spiral stairway to sleeping floor. For us no problem, but you should take this into account if you are handicapped.
We had a great time and we would stay here again any time.
