What a great place to stay!! Oia gets really crowded with tourists during the day and evening, but you'll feel far away in this cave house. Whenever we weren't out and about, we came back to the house just to sit on the porch and take in the view. The house is the last stop on a dead-end walkway, so you don't have to deal with a crowd to get back. I'd highly recommend taking Maria's suggestion for her to arrange a ride to and from the airport. That was super helpful! They were even able to store our bags for an afternoon before we left. If you're up for adventures, you must 1) Hike down to Ammoudi Bay, go swimming and eat at a tavern 2) Book the Santorini Food Tour in Fira (find through Air Bnb - it's amazing!) and 3) Hike from Fira to Oia.
