All the reviews on here are right - the marvellous location, the view, the access to restaurants and shops, the quiet, etc, etc. We had a wonderful week.
Giannis was very helpful beforehand and kept in touch by telephone when we were there, regularly checking that everything was OK. We didn't need any help, but it was great to know that he was accessible 24 hours a day.
We were really glad we took up Giannis' offer to arrange a transfer from the airport - we're normally very independent travellers - but we'd have struggled to find it by ourselves. Oia is lovely, but has thousands of corners, nooks and crannies!!
The sunset is not actually visible from the property, though you can see the glow on the Cladera cliffs opposite. Rather than turn right out of the property (where the crowds gather at the Castle), we turned left and took the back alleys to the top of the road to Ammoudi Bay (near the Ochre Wine Bistro). We had the sunset to ourselves (and it's a better view than from the Castle)!
Our favourite restaurants were Roka and Floga.
