The place is just like the pictures! I did not get to physically see the host, but they were always responsive and provided a pick up / drop off from / to the ferry, room was ready, supplies ready, including water and juice in the fridge... and a bit of rakia. The cave shower was what sold me on getting this place and it was all I hoped for!
Being the off season, the availability of food meant limited choices, but I did not starve, and actually loved wandering the streets in peace. I did two hikes, easily accessible from the apartment - to the cliffside monastery and the Minoan ruins. And make sure to visit the windmills at sunset. Amazing!
