We had a wonderful stay in Margarita's plac.
The apartment's location is great just 10 minutes walk from Oia. There is a supermarket nearby. The place was being cleaned everyday and has all you need, specifically if you want to cook at home. There are also 3 good restaurants nearby.

She was always responsive and easy to communicate. She arranged for our drive from airport and her assistant met us in the parking lot near the apartment, showed us the place and helped for carrying the luggage.
I highly recommend her place :)
