Great location and great host. This place is good for exploring the south of Santorini. The house is 3min from Perissa beach! (when you go out from the local bus at the Perissa Terminal, on one side you have the beach and on the other Onar Rooms, with beautiful mountains on the background).
At Perissa there is just one thing to do: go to the beach, but from here you can also get to cool little villages (Emporia, Megalochori and Pyrgos), as well as black, but also white and red sandy beaches. George is a friendly and calm person how is always ready to give advices and local tips (bike renting, restaurants). From here, you reach Thira in about 30min by bus.
