Ali's flat is indeed 5 minutes from the blue mosque away. We were really fascinated to live in historic area of Istanbul. Of course there were a lot of tourists and restaurants around. Therefore it was a little loudly even in the night.
Ali as host was very friendly and helped us to orientation in the city.
It is obligated to visit his shop round the corner. You can found necessary things for home or souvenirs for remember.
I would like to recommend the flat of Ali evident and hope to stay there again.
