I would love to stay in one of the boutique cave hotels, but am wondering if it is likely to trigger allergies/asthma. Anybody have any comments on this? Mold is a particular trigger for me. Also, would three nights be too much? And if not a cave hotel, can someone recommend a non-cave hotel in Cappadocia with utter charm and a feeling of history? Do you think three nights would be too long for this area?
