Exactly like the pictures. Clean and relaxing. You can't beat the views - we thoroughly enjoyed both balconies. Fanis and Tina helped us arrange a porter and transportation, and it all went off without a hitch. We were in Santorini for two weeks and walked all over. As far as a place to stay in Oia, I don't think you could pick a better location. Tourists are clamoring to get pictures of the views a little ways up from where this house is located; so, you are away from the crowds but right in the heart of where people want to see. We had a wonderful time.
A side note - we were traveling with our two daughters 8 and 6, and the upstairs couches/beds were plenty big enough; they even slept together in one a few nights. Also, having two balconies was great to enjoy some more private time. If you're traveling as a family, this place would work well! :)
