The apartment is in a very nice neighborhood of Napoli. The host was very friendly and quite fast to respond and assist.
What was disappointing is that there was construction in the yard and in front of our windows and we were not told beforehand. This lasted during our entire stay. There should be a serious discount for similar situations. They would start the work at 7 am, knocking, drilling, shouting, and all that goes with construction. One could not open the windows because of construction dust and the smell of a portable toilet they had in the yard for the construction site. The flat was also not the cleanest (bathroom and kitchen).
Otherwise Naples and Campania in general is the most friendly, vibrant and fun place to visit.
