The bnb is avtually just 2min walk from perivolos beach which I think along with Perissa is the most swimmable beach in Santorini. The sand in santorini is actually black lava stone that makes it little difficult to walk.
Julia and her family and staff were very helpful. Her son picked and dropped us from/at the airport.
The room was very comfortable and exactly as shown in pics with a small kitchenette. The water through in the faucets in almost all places of Santorini are saline so don't drink from the tap! The pool is a nice deep pool where u can relax. The food prepared by Julia is also very yum.
Overall it was a wonderful stay :)
