For anyone visiting Oia, I would highly recommend Mare Nostrum Santo. You could pay 4 times as much and not get a fraction of what you would here. The villas are private, luxury in a small package. We were only a 5-10 min ATV ride (strongly recommended) from Oia and while their sunsets are world renowned, I would say the sunset across the street from the villas is equally good. Breakfast was delicious, Penny went out of her way to take care of EVERYTHING we needed. Please consider this hotel strongly before you look anywhere else, you will not be sorry.
