The winery house is an amazing example of the architecture of Oia and Finnikia. Elleni, Costas and George (their new manager) were wonderful hosts.
We went during Easter holidays and hence their recommendations helped us experience the island to it's best. Eleni, Costas and George were always available to answer our questions and helped us with the car rental, finding tours and more!
The home itself is very comfortable. The house is great with little nooks and the decor is very minimal and tasteful. Even though it was a bit cold while we were there, we enjoyed breakfast and coffee in the lovely courtyard. The home is about 15-minute walk to the busy Oia village and 10 minutes from a convenience store. The biggest trouble would be to get tons of drinking water back to your house from the grocery store since tap water is not potable. The home itself is a 600 ft. walk from the main road where you would park your car. We appreciated that the kitchen was stocked with some bread, milk, honey, tea and coffee, given that we got there early in the morning! The home had a safe for our valuables which was really helpful.
We also found a little alley up from the house (across the main road) that joins the Oia-Fira walking trail and enjoyed viewing sunsets from there. We enjoyed exploring the little town of Finikia, down from Eleni's place as well. If you want to stay close to Oia but away from the tourists, Eleni's place is perfect.
