The sunset caldera cave house was just as described, a lovely oasis (especially at sunset) amongst an otherwise busy and touristy area. We slept with the windows open after the crowds had left Oia. Oia is the perfect spot to stay and relax for a few day (or more). We were able to take a catamaran cruise, visit a Minoan site, visit Ancient Thera, swim at a few beaches and have wonderful Greek food all from an absolutely charming home base. The power did go out for a few hours while we were there but the candles and lantern in the unit allowed us to have a romantic evening as the moon rose. Thank you! Oh and use the transport suggested by Ionna as the port can be hectic!
