I stayed four month in Gokalp´s apartment. Overall I had a great time and would come back given the price I paid at the times of the booking. Pros are definetly that the apartment includes a washing mashine, fridge, and stove. I just had to buy detergents and some extra kitchen utilities. Also, there is a nice balcony with a view on the Bosporus. The area is quite lively with lots of cafes, restaurants and the bar quarter nearby. As regards cons, the walls are quite thin, which depending on your neighbor might be an issue for one. Moreover, the communication with Gokalp was sometimes a bit rough and uneasy. However, Gokalp would always quickly react and help with my broken AC for instance.
