Catherine is an excellent host. The best I have ever stayed with on airbnb. She will accommodate all of your needs in Santorini quickly and efficiently and make you feel right at home. The neighborhood of her apartment is GORGEOUS! It is a traditional Greek Cycladic neighborhood and looks just like the pictures. The inside of the home itself is also AMAZING and the hot tub is to die for. She will assist you with everything you need getting around Santorini and will get you the best price.
Best Airbnb host I have ever had. I would not change anything.
