We weren't sure what to expect and were pleasantly surprised beyond our imagination. Couple things to note (all positive) that we did not realize.
They treat the 7 suites they operate as a hotel so there is a receptionist available from 8a-12pm. They helped us on multiple occassions with getting around, setting up ATV rentals, restaurant recommendations, etc... This also means there is daily Housekeeping service.
The steps in Santorini can easily knock the wind out of you. These suites are located in a perfect spot not too far down that make you fear the walk back up to the road.
They give you pastries every morning for breakfast, which we also didn't realize.
Long story short, this was a great stay and we hope to return one day!
