Hikmet is the best host on AirBnB that I ever had the pleasure to meet. He will take really good care of you. If you need anything, ask him politely and he will do everything he can to accommodate you. When we arrived, he knew the grocery store would be closed and we would have no food or drink. He got us some water and some fruits and tea and coffee. What a nice touch! Somehow our kettle was missing, he got us a brand new one the next morning. There is a washing machine for all to use in the building and a drying rack. But Hikmet decided it would be more comfortable for us if we had our own in our room. The next day he got us a brand new one. The internet was not very good for us and Hikmet tried to fix it but still slow for us. I told Hikmet that I believe that to fix this problem he would need a router per floor and not just one for the whole 3 story building. That was on a Saturday evening. On Monday he had a crew working to put a router on each floor and then we never had problem with the wifi. This is the kind of guy he is. Treat him like a friend, he will take very good care of you.
His places are not 5 star hotels, so just remember that in what you ask and in your expectations as well and I think you will be fine. He has many buildings and rooms so if one place is not to your liking, you can see with him to change to another one as well.
Also, he can help you with your plans for visiting the city and save you money. Don't make our mistake and talk to him first before paying big bucks with a travel agency. He also has places in Cappadocia so if you plan to visit this magical place, talk to him first as well.
