Catherine’s cave apartment was the perfect place for my trip to Santorini. It was close/walking distance to grocery, restaurants, and wineries, as well as important “touristy” things. Rosemary is an excellent restaurant literally three doors down from the apartment. Reasonably priced with spectacular views and tasty food.
Aside from what Pyrgos has to offer, the apartment is also close to the trailhead of Prophet Elias (the highest point of Santorini). I highly recommend the hike if you are into that kind of thing. Besides a monastery at the summit (be sure to dress appropriately for access), the views are amazing and unseen at any other place on the island. It was very hot the day I hiked, and no shade, but it was well worth it.
Centrally located, Catherine’s cave apartment is a perfect starting point to explore all areas of the island, including Oía, Firá, and Períssa. While I’m sure the bus works well enough, we rented a car, which was fine. Expensive, but fine.
Overall, I loved the apartment and will 100% rent again if/when I return to Santorini.
