Airbnb
The Cacoon cave was just perfect. It is exactly as described and in the photos. It has everything that you need as well as the most perfect view you could imagine. We spent our first night in Santorini in a US$600 a night hotel, but have to admit that we enjoyed our stay at Cacoon Cave far more. It is more basic, but just takes you back to a simple life so that you enjoy and concentrate on the simple things.
The location is perfect. If you're worried about the location, don't be. It is close to the main town of Fira yet five minutes walk away so that it is quiet and not touristy.
The cave in itself is not too hot as a large and powerful fan is provided.
There is a small kitchenette that enables you to cook small and basic meals. One of our favourite nights on the island was cooking a little meal at home and eating it on the balcony overlooking the stunning Caldera. The bathroom has everything that you need and a warm and powerful shower. On arrival there was even a bottle of wine and fruit juices waiting for us!
As for the fantastic host, she really made our experience. She kindly provided recommendations for a perfect local and traditional restaurant, as well as advising us on the best things to see in the island. Her recommendations were spot on and we really enjoyed everything that she proposed. On our last day we left for the airport and 30mins before departure realised that we had left out laptop in the room! When we turned on our phone we had a message saying that Elvira was waiting for us outside with the laptop. She had rushed 30minutes to the airport to make sure that we didn't leave it behind.
I have been doing Airbnb for a few years and have rarely met such a helpful and conscientious host.
DO NOT HESITATE TO STAY HERE IT IS AMAZING.
