Private Penthouse Terrace near Gramercy Park, Manhattan

I'm a midwest native who's called New York home for the better part of the past decade. I'm also someone who knows how rare it is to have private outdoor space attached to a Manhattan apartment. So I knew I wanted to spend time to turn it into a mini oasis. I have the aluminum Outer Charcoal Aluminum Loveseat and two Armless Chairs (that combination can be reconfigured into a section couch or daybed, as well).
