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.
