The cave house is really nice, it's exactly what the picture is and has all equipment you need. The place was amazing and it was relaxing place after a long day exploring Santorini however, the location is far from the Emporio town and Thera if you don't have car and not suitable for elderly people because everything is uphill. Another downside on the last 2 days of our stay the water pressure was low and flush of toilet didn't work properly, so ended up using bucket.
The best thing was our host, Tassos who was so lovely and very helpful, thank you for your suggestions which was very useful and for booking us to Metaxi Mas. Thank you again Perikles.
