Hasan is the best! Best in customer service. Location of the apartment is the best place to stay in Istanbul. Hasan responds quick and fast and provided us with more local information and everything that we need for our stay to be as smooth as possible. There is a bus that goes directly to Sabiha Gokcen Airport from Taksim and his place is only a 15-min walk from the bus stop. I DEFINITELY RECOMMEND THIS TO ANYONE WHO'S STAYING IN ISTANBUL
