We stayed for 3 nights at the villa, its location is excellent, next to chiaia funicular, and 1 street from the metro and central funicular, the vomero area is smarter than the central Naples too. Loved the building .. It is beautiful with stained glass and many plants, a lovely garden too. Room was fine,_ although the WiFi does not work I the rooms,_ only the lounge area. Breakfast is OK but quite basic, just coffee,_ juice and some toast and cereal, plus cakes (a bit sweet for my taste!)
Valentina and the housekeeper were friendly, just ask for info as there is no welcome folder with eg WiFi password.
One thing to note is the address, it is vicoletto not via, we took the main St and could not find the villa. It is on the small lane just to the right side of the chiaia funicular station.
