Cupola Suites is deceiving at first, located on the west side of Oia about .25 of a mile behind the main walkways of the picturesque Town overlooking the eastern cliffs. When we first drove up you pass neglected fields and incomplete construction projects but then we reached the walled in suites with beautiful views of the western shore and a private view of the magnificent Santorini sunset. The cave style suite has west facing windows with shutters to keep the hot sun out. There’s a private dipping pool perfect for cool off at the end of a long day. The interior is beautifully designed with built in couches and a cozy cave for sleeping. The bathroom is luxurious and clean with rain shower head high enough for even the tallest guest. The bed is a true queen size bed with dual reading lamps. The mattress was an issue for me personally. It was rock hard and very uncomfortable for me. My wife had no issues. I did manage to take some cushions from the couch to make it tolerable. This may not be issue for some guests who prefer a firm mattress.
