My husband and I stayed at the cave house to celebrate our birthdays and it was lovely. We stayed 2 nights but wished we could have stayed one more day, unfortunately it was unavailable. We were able to watch the beautiful sunset from the hot tub unobstructed by the other tourists. It was so nice not to have to fight for a spot like everyone else. All the pictures of the cave house are accurate. Giota and Alex are great hosts. Alex met us at the meeting point. He helped us carry our bags and showed us some places to eat. Giota gave us great suggestions for food and tours. She even set up a reservation for us to have dinner in Ammoudi Bay.
We also loved our breakfast that was conveniently delivered to our door at our requested time every morning. Our favorite was the savory pancake.
I would definitely recommend this place to my friends and stay here if I'm ever in Santorini again. The only downside was it is a bit of a trek from the bus stop or parking lot if you're not good with lots of stairs. We are in our 30s and did fine thanks to Alex's help with our bags. But I wouldn't recommend it for my elderly parents, anyone with bad knees or needing wheelchair access.
