Exclusive is the word for gorgeous, grand Gramercy Park and its surrounding neighborhood unless you’re the possessor of one of its 383 keys or are a member of The National Arts Club. And YAY–on Christmas Eve it’s open to all as long as they eschew riding bicycles, playing ball, smoking, drinking, walking dogs or feeding birds/squirrels while within. This two-acre domain is genuinely desirable to live near or jog around whereby you have the reasonable expectation of passing a celebrity of stage, screen, landed gentry or Wall Street who is doing the same if not strolling toward an eatery or boutique. You will find many of the latter nearby as well in and around other Gramercy regions such as Union Square and the Flatiron District once famous as Ladies’ Mile but now known for superlative boutiques and excellent home-decor shops. On the way to these more commercial parts of Gramercy, the cognoscenti will view with pleasure matchless brownstone mansions as well as a many nineteenth century houses of Anglo-Italianate, Greek and Gothic Revival architectures.
