Exceeded all expectations: super location, beautiful sunset views, and a terrace beyond belief. We were planning on going to a beach our first day there, but after seeing our terrace we realized that would be silly. Everything we needed and more was right there. Hot tub, sun umbrella, and lounge chairs complemented by a view of a Aegean-style church to the north and expansive seas ahead, and beautifully colorful bougainvillea in bloom.
Because it is built on a cliffside, there isn't much privacy on Oia terraces, but this place is as close as it gets. It is higher up on the cliffside so you can see folks below, but they can't see you. (Although tourists walking/stopping along the main road definitely can glimpse the terrace.) Another bonus that can't be overlooked - it is at street level, so no facing hundreds of stairs to get to your bed at the end of the day.
Our host helped with dinner reservations, but otherwise we had very little interaction. However, I am certain that he would have provided much much more assistance if we had needed it - he made himself very available.
