Mr Cas Hotel takes its name from a mysterious gentleman who was thought to be living in Pera, known for his stylishness and his hospitality. Rumor has it that he has thrown glamorous parties at the Guney Palas building, entertaining esteemed guests. Paying exquisite attention to every detail of his receptions, he has been engraved in Istanbul's memory with every trait from his taste in music, elegance and his delightful conversation. The apartment was the talk of the town not only because of its residents, but with the parties held here as well. Ladies and gentlemen, adding to the glamour of Beyoglu, gathered for receptions that would take days of preparation. It also used to be frequented by Yesilcam stars (Turkish movie stars) in the 1960's
