I didn't get to meet Maria in person, but the gentleman who helped get us checked in and situated was kind. It was raining pretty hard the day we got to the Airbnb, so it was difficult to find where to go until he guided us.
The Soul Cave House is located in one of the prettiest parts of Oia, and my husband and I took full advantage of being able to see the sunrise/sunset from right outside our door. We also liked that the Airbnb was close to a lot of things. We were in Oia during off-season so most places were closed, but it was still convenient to have the few restaurants nearby.
The place was clean, and we appreciated Maria's timeliness with our request for extra towels. We had all of the basic necessities that we were expecting, so that was good!
The only things we wished were better was more clarity on how big the place was. Strangely, it looked more spacious in photos, and it was pretty cramped since my husband and I are pretty tall. In addition, we were told that the cleaning lady comes every morning at 11, so we left our place unoccupied at 11, but she hadn't come. She came at 1pm instead, which was a little confusing.
Also, the bed was uncomfortable, and we found our backs hurting after just the first night. But honestly, I just ended up putting a pillow behind my back and that helped. The view and location made up for that.
