From the time we booked our stay until we left, Ermioni and her team were extremely responsive. She immediately connects you with their concierge service which makes this place feel like a true Airbnb/boutique hotel. They can make any reservations you need, including transfer and porter service, making travel a breeze. The place itself is immaculate, very clean, and comfortable. They provide light housekeeping upon request. The views of the caldera and private terrace were wonderful!! Note that the view is of the Caldera and has gorgeous views but not full sunset view, which wasn’t a problem for us because we wanted to experience sunset from many viewpoints on the island. Someone will meet you and check in to direct you to the cave house, providing a mini tour and directions of Oia along the way. I cannot recommend highly enough!!
