The Fisherman's Cavehouse is like a retreat within a retreat: Oia is surprisingly one of the quietest spots in Santorini, as long as you avoid town between 6pm-7:30pm).
We were there for a week and got exactly what we wanted. It is quiet, calming, impeccably designed and decorated in the cave house style indicative of the area.
What we didn't expect was for it to be arguably THE best spot on the cliff side, sun all day long on the terrace, perfect sunset view, and relatively private aside from a neighbouring terrace.
It is FAR superior to all the surrounding hotels/suites, we had people inquiring how we had a private plunge pool on a daily basis, & had to pinch ourselves as to how lucky we were. It is as close to perfection as you could want.

Panos is an incredibly friendly and attentive host, it was lovely to meet him in person and he really cares that his guests are well looked after, arranging porters and recommendations, even down to a specific local wine to try.

The plunge pool is a great size for 2-3 people, unheated which is perfect after all that sun, it practically became my home for the week. Watching the crowds gather at the top of Oia at sunset, you feel a little smug to have this private spot to take it all in.

Inside the Cavehouse is equally perfect: clean, minimal fuss, cool and tastefully decorated. We only used the main bedroom but we wanted for nothing, and cooked a couple meals in as a change to going out.
Breakfast was served daily and was just right, and the cleaner who looked after the place was lovely and we never felt bothered.

Whilst it may not be vibrant enough for everyone (Oia is practically dead after 9pm), it was perfect for a week of doing nothing and unwinding. We took daily walks down to Amoudi Bay, which is taxing on the legs but worth it! There's a rocky path that leads around the bay to a little rocky outcrop where people cliff dive, swim & snorkel. We never once went to the beaches on the Caldeira as this spot had the best views. After a swim we went to 'Sunset' restaurant for the best seafood lunches before hiking it back up to town (please avoid the mule rides, they're kept in bad conditions and it's unethical in this day and age).

We'll definitely be back someday, and thanks to Panos for helping make our weeks holiday absolutely breathtaking, he's exactly why AirBnB is so successful.
