Great flat, in a calm street but close to a busy street where can find all you need (food, ice cream, pizza to take away, etc) and a bus stop direct to downtown. Posillipo is full of possible acivities (kayak, beach, boat trip, etc).
Flat fully equipped.
Host available when needed and giving advice. Some nice attentions on arrival such as fresh water in the fridge, croissants for first breakfast.
