Sutton Place is a little enclave that runs from the East River to Second Avenue, 52nd Street to 59th Street 

Sutton Place in the East Fifties is quite the retreat from bustling Midtown Manhattan — a stretch of elegant prewar co-ops and townhouses, this is where Marilyn Monroe and Lauren Bacall rented their penthouse in How to Marry a Millionaire. Running parallel to First Avenue, Sutton Place (which is called Sutton Place South below 57th Street) has some wonderful prewar apartment buildings with grand river views. This tiny area has some green too, with two parks located just five blocks from each other.
