We had a great time in Volkan's apartment. It lies in a nice quiet neighboorhood, but still very close to the Sultanahmet Square. The apartment inside was impeccible, with clean towels, sheets etc. I guess it's renovated recently. Although we didn't meet Volkan in person he was still a good host. He was easy to reach and he asked regularly if everything was okay and if we needed anything. The people of the restaurant downstairs (the Meat House) were very kind and helpful. We would surely recommend this place.
