Al Capone once hired out the whole 6th floor, Graham Greene used room 501 as a setting for Our Man in Havana, and the Mafia requisitioned the place as operations center for its pre-revolutionary North American drug racket. Nowadays the Moorish Sevilla still packs a punch, with an ostentatious lobby that could have been ripped straight out of Granada's Alhambra.
Spacious rooms with Sevillian tiles on the headboards get periodic upgrades, and the 9th-floor restaurant where you're serenaded by violin over breakfast is an 'experience,' but you're paying more for history here than modern facilities or snappy service.
