Kemal is really super host. We were 6 people and the apartment was big enough for us. It was clean, nice interior, comfortable beds and even sofas were very comfortable.
Location is super quiet and super central. Walking distance (5 minutes) to Istiklal street, on the opposite side 5 minutes to Kadikoy (by walk). Walking distance even to eminonu. Allover, really the best location and apartment. Price worths it. We will recommend it and definitely back here again.
