Kalen is a fantastic host. The place is centrally located and close to all the major places to see in Istanbul. Most of them can be reached by foot ! Kalen also gave us tips and suggestions about the local places around as alternatives to the busy crowded places which were expensive. It made our day out in Istanbul way easier. Kalen also took time to show us around the area without which, we would have been lost. His knowledge about the area along with suggestions was so valuable to us. Also knowledgeable were the discussions with him about various topics. He gave us clear directions on how to reach his place without any ambiguity at all. His place is cosy and comfortable with all the amenities. I would recommend his place to anyone visiting Istanbul.
