We came to Santorini in December and therefore had a quieter and less touristy stay.
Vivi's place is lovely and just a stone's throw away from the main streets, but tucked away so that it's quiet. It is well-decorated and clean, and has a very complete kitchenette.
Vivi very helpfully arranged transport for us to and from the airport and also recommended a few places for us to visit and eat which was helpful in December/January when most of the restaurants were shut.
Would be very happy to go back again when I can.
