The flat big, clean and fresh. All amenities are present as listed in description. Istanbul tend to be noisy city, but this apartment IS quiet, so we finally could sleep well at night) It is also safe and has good location. The supermarket/laundry/pharmacy/buffet/barber's is 1-2 mins to walk. Istiklal street(heart of Istanbul) about 3-5 minutes to walk. On the sibling street every sunday big "bazar" happens where you can feel spirit of the east market diversity. It is organized by locals for locals so it is pretty cheap.
The flat is definitely the best one of 3 we have already rented in Istanbul.

Volkan is a great host. He always stays in touch with you and tries to help, so if you have any problem or question related apartment or not, you will get the solution in 2-3 minutes. It is worth mentioning that my girlfriend had a toothache and Volkan made a dentist appointment for us and took us there. You are in good hands when dealing with Volkan!
