The rooms are cold and humid (this is partially due to the nature of those structures I guess). The towels were all the time wet, could not dry. In the cave room, the bathroom door was not closing, we had to use a small table to close it. Lightning of the rooms were very inadequate. WiFi could not be used inside the rooms; we should go out to be able to get some signals. Staff is helpful. But you should be careful if you ask for some information. They try to send you to some places with which they have connections. So, whatever they say, try to stick on your own plan. I would not suggest the guiding tour of the hotel (Bridge of the world) for Cappadocia daily tours. We were not satisfied by the guide and the tour.
Me and 3 of my friends were stayed in two different type of rooms: a Cave Room and an Arc Room. Arc Room is relatively better than the cave one. The location of the hotel is good. Indeed, it has a nice panoramic view. Patio of the hotel was very good for chilling out. The breakfast is good. Staff is nice and kind. They let us to extend one of the rooms check out time.
