Legendary places plucked from the pages of popular novels and the lives of fiction writers need little input from visitors to evoke their storied Graham Greene 's Hotel Sevilla , where Our Man in Havana went to meet his secret service contact , and Hemingway 's favorite watering holes ( El Floridita and La Bodeguita del Medio ) and the Hotel Ambos Mundos , where he penned much of For Whom the Bell Tolls .
Hemingway wrote a lot of For Whom the Bell Tolls at the Hotel Ambos Mundos .
