I recently visited Cappadocia and found it great. As I met some very nice people that helped a lot - I would like to recommend them.
We were a group of 6 people. We slept in Ϋuksel hotel (www.yukselhotel.net). It's a new hotel in the center of Goreme. It is owned by Ϋuksel (an elderly guy, speaks good English) and his son Mustafa (also very communicative and helpful). For example, despite the fact that the hot-air balloons were fully booked for a few days, they manage to arrange for us a place. We like to play Bridge so he arranged a table for us on the first floor, etc.
We also met Faruk (he arranged for us the balloon). He works in a motor agency (Oz cappadocia). We rented little tractors from him for a ride in the surrounding valleys. It was very beutiful.
At last - food. By accident we found a restaurant on the way from Uchisar to Nevsehir (Asiyan restaurant). The owner (Ali Yedekci) is very nice. He serves fresh salad (really fresh!), grilled fish and fresh French fries. Great place.
