After spending 10 days in the flat, all I can say is that Dogan has been everything you expect from a host. I was impressed by the great hospitality and the quick response shown by Dogan, and of course the delicious free breakfast prepared by Çimin everyday. Balat is located in Fatih district from which you can reach all of the historical places (Aya Sofia, Blue Mosque, Topkapi Palce...) very easily. The bus stop is just 2 minutes away from the place. The neighborhood is full of antique shops, nice cafes, and restaurants. When I visit Istanbul again, this place will definitely be my choice!
