That view is absolutely magnificent! More so than the pictures could possibly capture. We had very good communication with Maria, who arranged for a taxi to take us from the airport to Oia where we met a gentlemen who helped us with our bags and showed us to the cave. The cave is small but very clean and comfortable. It's a ways down one of the staircases from the main walking street, so it is very peaceful and quiet (we were there in the off-season so it was extra quiet, but given the location, it would likely be one of the quieter spots even in the high season). It's on the south side of Oia facing south into the middle of the Santorini islands, so the views are amazing (no direct sunset view, but that's probably a good thing because then you don't have to deal with the sunset crowds). Overall, a lovely little spot recommended for a couple.
