Gramercy is one of New York’s most exclusive neighborhoods, and according to TimeOut, the most interesting, too. The reason? Well, part of it is off-limits even to born-and-bred New Yorkers. At the heart of Gramercy is its namesake park, Gramercy Park, which is iron-gated for certain resident access only. This private enclave is one of only two private parks in New York City. Since 1844, Gramercy Park has been accessible only to a select group of keyholders from the 39 surrounding townhouses. Each key costs around $350, and there are only 383 keys in circulation.
