The hosts were very friendly and prepared a lot of things for me.
The rental was very inexpensive, even though it is located near the entrance to the center of Kadikoy. I highly recommend it to anyone who wants to experience the center of Kadikoy. There are countless cafes and restaurants. Also, the ferry and metro stations are close by so you can easily get to the European side of the city.
The rooms are spacious for the center of town, and there is a desk in the living room for working. You will be comfortable even if you don't go out during the day.
The only problem I found was the internet speed. Depending on the device, it is hard to connect in the room. I measured it in the living room where the router is installed and it was about 3 MBPS on the down side. I already told to host, but the problem is on the part of the telecommunications company and cannot be easily resolved, host say.
