Triple penthouse with private outdoor space! This unique four bedroom, three bathroom coop loft is available on the private market and ready for a lucky new owner. A keyed elevator leads you to your semi-private landing, and onto the ground level of the apartment. On this floor are 11-foot ceilings, an enormous open loft space with powder room, southern-facing windows, an open, SieMatic vented chef's kitchen, an office, a den, and a separate dining area flanked in gorgeous built-ins. It truly screams Flatiron loft! The second floor has two bedrooms and a full bathroom, as well as a full-sized laundry room and dog washing station. The top level of this triplex is the primary suite, as well as private terrace. The bedroom is large, with en-suite bathroom inclusive of a double vanity, soaking tub, and stall shower.
