The cave house is lovely and much bigger than we expected. It has 3 bedrooms and 3 bathrooms (one suite is upstairs). The hosts picked us up from the post office and had a porter on the way in and out. The hosts gave great local tips. The house itself is in a great location, just one street away from the main area but nice and quiet. There are local donkeys who carry items in the street which you can hear in the cave house - but this is likely the case in any place in the main oia.
Close to the house is an area of about 200 steps down towards the bay and to the left is a walking path that takes you to a rocky beach which is wonderful for swimming. I saw fish and it was lovely!
The hosts are very quick to respond to any inquiry.
