Davut is a great host. He is warm and very friendly. The flat is in Kadikoy, the heart of the Asian peninsula of the city. Its in the walking distance to all means of public transportation.
The badroom was quite although the neighborhood was lively.
The mattress, pillows, bad sheets etc were all clean and comfortable. The curtains was effective as needed for blackout. So I had a resting sleep. I would definitely like to stay there whenever I come to Kadikoy, Istanbul.
