Live in style with a highly desirable Madison Avenue address, in this fully renovated, 5-story, 3240 square foot townhouse - featuring an owner's tri-plex PLUS a separate one-bedroom duplex garden apartment, well-suited for rental income, or use as an additional owner's residence, an incredible work/office space, or as a spectacular (and fully legal) Airbnb unit. And... all this comes with an exceptionally low yearly real estate tax - approximately $2,874 per year! The owner's tri-plex offers 4 bedrooms (or 3, plus a sitting room/library/office), plus 3 luxurious full bathrooms and a parlor floor powder room. Each lifestyle and "Architectural Digest"-worthy-detail has been carefully considered and implemented, modernizing this 19th century townhouse into a 21st century classic. Entertain in grand style, welcoming guests into the loft-like parlor floor, featuring a high-ceilinged living room and elegant dining area, as well as a spacious eat-in kitchen with oversized island, stainless steel, high-end appliances, gleaming quartz countertop, a convenient and well-appointed powder room, and a windowed rear wall and glass doorway. Additional entertaining possibilities are available, with convenient access from the kitchen to the large outdoor deck. A adjacent spiral staircase leads down to a private garden, with unlimited options for "botanical pursuits", grilling, or simply lounging in your own secret garden. Up from the parlor floor, a modernized traditional stairway ascends to the luxurious, full-floor master suite, complimented by an en-suite spa-like bathroom, featuring double sinks, an oversized-soaking tub, a separate glass shower with overhead rainfall fixture and multiple body sprays, and a generous, walk-in closet. An "ultimate retreat", this master suite features a sun-bright sitting room/office/bedroom, with an iconic (and landmarked) Harlem church directly across the street - its translucent, multi-colored stained-glass windows, directly opposite 2040 Madison Avenue, offering unparalleled privacy and exquisite vistas from this room. The top floor, sun-drenched courtesy of a large, centrally-located skylight, consists of two large bedrooms, each with its own well-appointed, en-suite bathroom; and a laundry room. In addition, thanks to unused air-rights which will transfer with the sale - this top floor presents endless opportunities for creating a wonderful penthouse addition, or, more simply, a rooftop garden and terrace - only one flight up! The two lower levels of this townhouse comprise a separately accessed, self-contained, garden-level duplex apartment, with a garden view from the bedroom, an EIK with island, stainless steel appliances, and a lower-level bar and recreation/ entertainment area. This fully finished lower level adds an additional 810 square feet of highly useable space. 2040 Madison Avenue, renovated to a high standard of excellence, with central heating and cooling, individually zoned for each of its four residential levels, is conveniently located a short walk away from the Metro North, 2,3,4,5 &6 subways, not to mention private parking structures - allowing easy access to "the rest of Manhattan", upstate, Connecticut, and the world! Multiple shopping and dining options are, similarly, a brief stroll away, including Whole Foods, Red Rooster, Chez Lucienne & Sylvia's, with Shake Shack, soon to come - not to mention neighborhood parks/playgrounds, the Harlem Rose Garden, and the entire rapidly evolving 125th Street corridor, a world-class arts, cultural, and entertainment destination. Come and enjoy this incredibly diverse, historically rich, highly energized, constantly evolving - and easily accessible - community of Harlem from your venerable, yet contemporary; stylish, yet incredibly livable; high-end, yet reasonably-priced, Madison Avenue townhouse!
