My wife and I really enjoyed our stay on Santorini, as well as the caldera views from the studio and the town on Firostefani (about 1km North of Fira). However, we had several issues with our stay.

First, I had trouble contacting the hostess, and tried several times before we arrived, but got no response. This was odd, because she had been very responsive when I book the room. Secondly, we never met her until she asked us to leave so the cleaners could prepare for the next guests. We didn't know anything about the rules because there was no information sheet in our studio. We borrowed one from another guest only to get the wifi password. The other guest also mentioned not to drink the water (it's desalinated ocean water, not good for drinking).

Third, there was a strong sewage smell in the apartment about half the time we were there. Also, there was no "BNB" provided as I recall, just a water and a yogurt each for my wife and I.

Overall, our stay wasn't bad, but it wasn't as good as I was hoping. This was not the cheapest place on the caldera, but I got it because there were great reviews. Maybe we got a bad experience.
