We enjoyed our stay in the cave apartment very much. The view is breathtaking, the apartment is cozy but comfortable, and Elvira is a very friendly, helpful and welcoming host. The apartment is very well-located in Firostefani, a small, quiet village just up the road from Fira - it's about a 10 minute walk from the apartment to Fira, along a pedestrian-only path that lines the caldera. We spent one afternoon hiking in the opposite direction - from the apartment to Oia, along a hiking trail overlooking the caldera - spectacular views! They say the sunset-viewing is best in Oia, but we thought the sunset view from the cave apartment was better.

A couple of notes - there is no door separating the main living area from the bedroom in the back of the cave - and we had some trouble with the wifi, but that seemed to be the case for Firostefani as a whole, not just the cave apartment.
