The hotel also has a museum (as it should) to showcase the history and grandeur of it's heritage and the guests who stayed there like Mustafa Kemal Ataturk. Allegedly, Agatha Christie wrote the book Murder on The Orient Express during her stay at the Pera Palace in Istanbul in the 1930s. Greta Garbo, Alfred Hitchcock and King Edward VIII also loved to hang out at this Art Nouveau and Oriental styled hotel.
