We booked this incredibly last minute for an overnight stay for my birthday. Tina & Fanis were quick to answer and were really helpful. They arranged a transfer and a meal at the lovely Ammoudi restaurant. The Caldera was gorgeous and authentic with modern furnishings, so we had everything we needed With the most beautiful view of the caldera. The main bedroom was stunning. There are a number of uneven steps on the way down to the caldera ( which is common in Oia) so wear comfortable shoes. The location was great and close to everything. I will definitely recommend.
