A celebrity's love affair with a specific hotel tends to come and go faster than gossip on TMZ. But ever since Hotel Cipriani opened its doors in 1958, it has attracted a high-wattage clientele. Old-school names like Jack Nicholson and Anjelica Huston mingle in the hotel's "Golden Book" with hot properties like Clive Owen and Jennifer Lopez. Accessible only by boat, this waterfront property is perfectly set for those seeking seclusion. Everything from the personal butlers to the private gardens is discreet. The glass-enclosed Palladio Suite is a favorite with the rich and famous, but there's no need to try your hand at stalking. Simply book a table at Fortuny Restaurant, and you're sure to spot a bigwig before the night is through.
