The Cave House at Ersi Villas is a nice place to stay. Be aware that the bed is only accessible from one side as one side is against the concrete wall in the alcove. This may not suit everyone and it is difficult to get in or out and also to make the bed if you like the sheet tucked under tight. The pool is great and the location is superb for visiting Firastefani and Fira. Visitors will obviously be aware there are steps and hills to climb to go anywhere by foot. Santorini is unique and the views make it worthwhile. Elias is a good host and I’m sure he will continue to develop this place to make sure you have a wonderful stay.
