We stayed in ISIK's house for almost 6 days, it was a very memorable and nice experience. Isik checked us in personally at late night and gave us all the necessary information, he left us a stanbul card which turned out to be the most usefull thing there for us for transportations. The house is clean and nice and it's in a very strategic place of city, near Taksim Metro station and Isteklal street. All in all, I highly recommend Isik and his house to the future guests.
