Mahmud's appartment is more than we expected. We had a great stay. The apptmnt is really near just about 5-10 mins walk to most of the attractions such as Blue Mosque, Hagia Sophia, Basilica Cistern n Grand Bazar. It is also near to the Sultanahmet tram station. Mahmud is also a very good host. He He is very helpful when we are in need thus everything went smoothly throughout our stay in Istanbul.
