Nothing... maybe the curtains were a bit too thin so there was plenty of light in the morning, but we wanted to wake up early, right? And this seems to be a common thing in Turkey.
The place was beautiful, well kept, and in a great location. The owner Erdogan was very helpful, gave us plenty of information and advice, and helped us reserve various activities, and went beyond what was expected of him (he offered to drive us to the start of a hike, gave us a discount as we could not do a ballon trip -even if it was only because of the strong winds-). The rest of the staff were very kind, the traditional turkish breakfast buffet was very complete, and the views from the roof terrace are impressive. Our cave room was beautiful, well decorated with lovely turkish textiles, traditional but at the same time with taste and very luxurious.
