Coccoon is as described - a cozy cave room with a lovely terrace. The room has been very artfully done up with every space optimised very aesthetically. Our hostess was very helpful with local inputs and her suggestions on food, when to walk to Oiwa or on bus routes - were invaluable in making our Santorini stay an outstanding experience. There was daily housekeeping and the welcome amenities were plentiful.
The terrace views are lovely - though for a more complete sunset view, one should walk up the lane outside the house.
In our 3 night stay, we shifted to another room which had a window overlooking the bay - and it was wonderful to see the full moon sparkling on the sea and a 6am cruise ship coming in with the moon shining like a sun. Just lovely.
Two things to keep in mind : There are steep steps to reach Coccoon & they can be challenging with luggage.
Secondly, the rooms while being very atmospheric, are rather tight on space - whether for luggage or at the kitchen counter.
