This shot shows traditional waterfront houses in Heybeliada on the Princess Islands in Turkey. 

One of the few instances where a building's facade & signage was not changed - this is the Hotel Pera Palas in Istanbul. The real Mustafa Kemal Ataturk (portrayed in this episode by Ahmet Levendoglu) stayed in this historic hotel in 1917, and today his former room houses an exhibit on his life. Ernest Hemingway and Agatha Christie were also regulars at the famous hotel.
