Ammoudi Bay was a great place to donkey/people/boat watch without being in the middle of Oia. Sleeping on a fabulously comfortable bed, hearing the water crashing on the rocks below was a recipe for perfect sleep. There is a great swimming spot 5 minutes walk. The kitchen was well stocked, and we were able to enjoy breakfasts out on the patio. The pools were the icing for us because the sea was not super warm, and the pools allowed us to dip and sun ourselves.
I came with my daughter, and we are very active. The 238 stairs up to store was part of the adventure for us, but may not be for everyone. 10E to get a ride up the hill. Not sure if there is parking if you rent a car, which we did not. The girls helped us out with reservations for Armeni Bay (which is a must), and were always available when we contacted them. This is by far my favorite Airbnb spot yet!
