We had a really great time at George's place! The house was very clean and fully equipped. For me Kamari is the best location to stay on Santorini - in September very peacefull, far from crowded cities, very close to the beach, shops and nice (not expensive) restaurants with a seaview. George is very nice and helpful! :)
We loved eating and drinking wine on the little porch outside, but it is worth to mention that the main road next to house is quite load and busy espacially in the evenings. And one more little thing: the bed was quite uncomfortable for two person, because of combination two separate mattresses, not big one.
Except that, everything was great! We really recommend this place :)
