The house is gorgeous and well maintained. It feels very safe and luxurious. The tub was heaven on a hot day (it was a cooling tub but they raised the temp for me as I'm always cold!) The layout was spacious and comfortable and the lighting quite nice. The many sitting spots around the house and outside areas was excellent. The kitchen was efficient and the knives and cooking tools very good.
If you're not afraid to drive in Santorini, get a very small rental car or make day trips with few destinations in mind on the same day by bus or transfer arranged by the host. The buses are great for getting around but unpredictable on that part of the island. Personally, I'd opt out of the cleaning service unless you're there for a week or more. I wasn't a fan.
I will remember the views from the house and the walk to one of the best sunsets I've ever seen due to the panoramic view. STUNNING. It was a memorable stay.
