Gramercy Park, a traditional and sophisticated Manhattan enclave, features some of the more expensive real estate in the city including a mix of Victorian brownstones, and stylish high rises. This tranquil residential neighborhood is bordered by the East Village and the Flat Iron district. The tree-lined streets aren’t the only appeal of Gramercy Park, however. The namesake of the neighborhood is a park requiring a key to access it, only available to residents. While the neighborhood is primarily seen as pristine, quiet and relaxed, it is near Union Square Park, featuring the Union Square Green Market.
