The Cave has been the best place we’ve stayed throught our entire trip. It is right in front of a private beach and the Cave itself is really fresh, so hot is not an issue. It is really spacious and it has a little kitchen where you can cook breakfast.
The sea sound is amazing and really calm and helps you sleep and relax.
I would suggest bringing special shoes to swim since there are a lot of rocks and diferent sea animals that can injure you if you walk past them.
I would totally recommend this experience for anyone that visits Santorini!
