Mahmud was a great host. Very knowledgable, totally reliable and with a lovely apartment in the perfect location for the top Instanbul sights. Blue Mosque, Hagia Sofia and Topkapı Palace just a few minutes walk away. Restaurants and tram stop also nearby.
Mahmud arranged taxis for us, supplied water for our whole stay and left food for us so we didn’t have to find shops straight away.
Thoroughly recommended.
