Eleni and her husband, Costas, were as accommodating as we could've desired. We were probably not their typical guests. Nine of us including three kids from 12-3 yrs old. They showed great patience and understanding in assisting us in a multitude of situations.
From meeting the second group to arrive with a donkey to carry their luggage, which was a treat for the kids to great suggestions of things to do with kids and to minimize the inevitable tourist traps.
We used their facilities to prepare light evening meals if we had made lunch the heavy meal of the day. The main unit was large enough for us to all eat there, dance there and play there. It had the best equipped kitchen of the three available.
Eleni also got us a private viewing of the tiny church next door. We followed most of their suggestions and they were generally correct. The three couples had private meals and their commentary on the restaurants aligned with Eleni's and Costas' thoughts on these places.
The Wineryhouse is an unusual property as it's set in this very small village of Finikia with no access by cars. Be ready to walk and not have access to the amenities of a hotel. The whole island of Santorini requires a lot of walking up and down. Bring comfortable shoes. Be prepared to get a little lost too when walking the first night or two near the Wineryhouse. Roads aren't well marked either. No matter that's part of the fun of this type of vacation.
Two notes: the steps to the upper unit are very steep (though it has it's own separate access so this only comes into play going down to the other units.) Don't do it if you're drunk.
Second the pool is very small. We closed it off to protect the three yr old.
By the end I felt a very close connection with our hosts and would love to spend more time with them. Try this if you want to enjoy Santorini and not be immersed in the touristy hubbub.
