We cannot recommend Templars's Home enough.
The apartment is exquisite and in a wonderful area of Naples which is walkable to the seafront and lots of attractions.
Alessandra was the perfect host, going out of her way throughout our visit to make our trip the most enjoyable it could be, such as providing a full brief of Naples upon our arrival and letting us leave our bags before and after check-in.
We will definitely return next time we are in Naples!
