We enjoyed our stay in Santorini and the views are unbeatable. Watch the sunset on one of the verandas - I recommend the highest one. The cave stays cool don’t worry so much about that. Eleni was very responsive and offered a lot of services that I recommend taking advantage of - sunset volcano tour, dinner reservations, etc. I’m tall and I hit my head on different doorways or in the bathroom or kitchen area a couple times, so be careful of that if you’re tall.
