Konstantino is a wonderful host and his place is exactly as pictured: clean, bright and traditionally Greek! His nephew, who lives upstairs, was very helpful and even gave my husband a lift to the rental car place for us to get a car. The place was stocked with amenities, extra towels, and clean linens. A maid came to clean 1x per day and also did our laundry upon request, which was above and beyond service!
The apartment is centrally located on the island, but not necessarily in a neighborhood or a lively part of town. You will definitely need a rental car or ATV during your stay to get anywhere, and Oia is at least a 45 min drive.
I highly recommend Shades of White, it's an extremely good value and a lovely place to stay!
