I just returned from a three-week stay at Cerith's in Istanbul. I was there to do fieldwork for my master thesis on politics and political uprising. Cerith is a curator and he was very, very kind and a huge help. Both concerning my work there and on a personal level he was a BIG part of making my stay in Istanbul the best it could possible be. He is such an interesting, kind and helpful person. His English is perfect and he knows a lot about the Turkish culture.
He introduced me to many of his friends and everyone welcomed me with open arms.
Cerith's flat is cosy and neat in a vibrant and colorful neighborhood, and he knows a lot of Istanbul's hidden treasures (bars, restaurants, galleries, museums).
I can only give my warmest recommendations. I will definitely come back and visit him again.
If you want the whole Istanbul experience Cerith is the perfect host!
