We were 2 families (4 and 5) and the house had 2 independent apartments and shared the terrace.
The place is amazing and so the little town of Finikia.
We got great restaurants and beaches recommendations from George.
The house is walking distance from Oia (15min) but we recommend a car to visit all the beaches.
As states in the place description you have to walk from the house to the parking around 5 minutes (up and down in the streets of Finikia), so don't bring big luggage. Definetely a place to return to!!
