My boyfriend and I stayed in the Sensyo Caldera Soundscape room and it was stunning! Most magical view to wake up to (the photos really don't do it justice), and a true Santorini cave experience. I also loved the area Firostefani much more than the main town of Fira, which was far too crowded (it's still only about a 15 minute walk to Fira so very easy to get to!) Everything you need including a mini mart and some good restaurants. There are quite a few stairs to get to the house but it's worth it. The only thing I would say is even with the fan on, it got quite hot because there are no windows. We just left the door open as much as possible and it tended to cool down! Would go back in a heartbeat, truly the most amazing view possible!
