Right in the heart of Sultanahmet, in the backyard of the Haiga Sophia, a few minutes walk to the train station and only a couple stops away from the bazaars, ferries, and other attractions.
Volkan is a great host and was on site almost every day to answer questions and provide services. He arranged VIP trips to other cities in Istanbul and to/from the airport at really good prices.
We can't thank him enough for his patience and hospitality.
