The room is exactly like you see on the pictures. It is clean and equipped with basic kitchen appliances. Host communication went smooth and he replies promptly to any requests. Most of the time there was a very nice lady on spot on the first floor, who is taking care of the place. She was helpful for basic requests (you will need google translate though). Check in/out is fairly easy. Quality is good for the price.
The area where the rooms are located is quite noisy, full of small cafes on narrow streets. Hence, you have a wide variety of choise for food nearby, but be prepared for street noise in your room.
Public transport connections, including Besiktas ferri station is within the few minutes walk. There are also few parks around for chilling out (Yahya Kemal park was my preference). If you go to Abbasaga Park, take some cat food with you as cats are the hosts there.
