My family (6 total) and I celebrated my 50th birthday at the 180 degree view villa and we had a fantastic stay. The villa is in a perfect location for relaxing and taking in the unbelievable caldera view, which stunned us as soon as we arrived. The house had everything we needed, was very spacious considering that it is an actual cave, and the beds were very comfortable.
Everything you need is in close walking distance, the restaurants in Firostefani were wonderful. It’s also situated perfectly to easily visit other areas of the island. We hiked out to Skaros rock, walked down through all of Thira and took a 15 minute taxi ride to and from Oia in one day. The host was very helpful and responded immediately to any questions we had, as well as arranging effortless pick-ups on arrival and departure. There are a lot of steps all over the island (the hosts did provide much appreciated help with luggage) which most of us did not mind. Just be aware of that if anyone in your group has trouble with walking up and down stairs.
