The very nice "Old Vourvoulos house" is located in a residential area in Vourvoulos a bit away from the hustle-and-bustle in Fira and central to all sites on the island. We spent here 4 days in August and enjoyed our stay very much. The house is very spacious with a nice porch and comfortably accommodates 4 persons.
Tania has organized the transport from the port and Kyriakos, the owner, has welcomed us and explained us all the details about the house and gave us plenty of recommendations about what to do on the island.
This house is highly recommended, unless one wants to stay directly at the beach or somewhere in Fira or Oia along the caldera side of Santorini.
