While I didn'tmeet Kostas, Vasilis took great care to meet me at the post office and escort me to the apartment as well as escort me back when I left. Staying in Oia for several days offered the opportunity to see Oia early in the morning and after sunset, and to see the beautiful sunset several times. The studio is exactly as the photos show and very comfortable. For older folks like me, Oia involves some steps but I didn't find them too difficult to navigate, and the apartment requires climbing down a flight of stairs to the courtyard. Thetrue beauty of the apartment is the view, which is from shared rooftop overlooking a church and a windmill, with a direct view of the sunset. I rented a car and found parking near the post office but I had to coordinate my comings and goings to avoid the sunset viewers. This wasn't a problem though. Also provided were eggs and a loaf of bread each morning to make breakfast, and daily maid service, which were nice treats. I would definitely recommend Kostas place if you are planning on an Oia stay!
