Mehmet is a wonderful host. He is willing to help with anything and he goes the extra mile. We loved staying in his Airbnb. It is completely as advertised. Within walking distance of all the major tourist attractions e.g. Blue Mosque, Hagia Sophia, Topkapi Palace, Islamic Arts and Culture Museum, Archeological Museums and the Islamic Science and Technology Museum. The tramway is also within walking distance for easy travel. Just to note, walking from Mehmet's place toward the sights is quite steep uphill, so may not be for people who struggle with brisk walking for extended periods of time.
I would suggest following Mehmet's guidebook for restaurants and attractions, we loved every suggestion.
