This place is a gem!!!! We only had 24 hours in Santorini, but wish we could stay longer. The place is clean and the view is absolutely stunning! The stairs to get to the house can be steep and narrow so make sure to take a comfortable footwear.
Maria was very nice and prompt in responding to our questions. Because there is no street address for the cave houses in Oia, make sure you connect with Maria before you arrive to arrange your check in. Vasilis who met us at the shuttle drop off and took us to the house was very thorough in explaining the house rules, and he suggested different places to go which were all good.
If I ever have a chance to visit Santorini again, I will not look for any other place but this one to stay!!!!
