Vivi's place was perfectly located in Fira. She met us at the very close parking lot and also gave us tasty baking and local liqueur for us to try.
We stayed in the winter and Vivi's place was by far the warmest one of three we stayed at on the island (far warmer than most restaurants and other buildings). The space heater was much appreciated. Very cosy! There is a market down the street and even a washing machine. Caldera is a 6 minute walk away.
Amazing value! We'd stay again.
