With a great Back Bay location, plenty of space and amenities galore, Unit 6 at 73 Marlborough St. is a timely treasure.

Neda Vander Stoep of Coldwell Banker Residential has listed this south-facing, 2,078-square-foot penthouse duplex for $2,395,000.

The best way to describe this home is “classically elegant.” Lofty architectural ceilings, beautifully-detailed millwork and gleaming hardwood floors depict a traditional feel while skylights, sconces and soffit lighting add contemporary flair.

The favorable floor plan, grand and gorgeous, is ideal for entertaining.

The spacious kitchen, well laid-out and easy to move around in, is simple, yet chic.

The area centers around a long island with a built-in six-burner JennAir glass cooktop, ready for culinary capers. The Thermador oven and dishwasher flank the centered sink in the elongated L-shaped counter lining the back wall. A refrigerator that has the capacity to hold plenty of fresh and frozen food sits at the shorter end.

The island countertop coordinates with the large custom built-in beverage rack, adding a splash of color. The plantation shutters on the large windows and the glass-fronted upper cabinetry are admired architectural details.

On the opposite side of the island, with seating for three, there is plenty of room for an informal dinette set, if desired.

The spacious dining-living room has a large wood-burning fireplace surrounded by marble and trimmed with wood, anchored with six tall built-in bookcases with low cabinets on either side.

On the opposite wall is a space carved out for a formal dining table. The two walls are lined with wainscoting symmetry. A dry bar features mirrors on three sides of the inset. Placing a plant or decorative vase on the shelf not only adds color and texture, but intensifies the reflections from the mirror, adding another aura.

The custom bump-out windows at the end of the room are most unique. They have side and overhead mirrors which can reflect a colorful array of décor and vistas. The windows overlook the quiet beauty of Marlborough Street.

Between the kitchen and the dining-living room is the foyer with a coat closet and a large half bath. The stairway elegantly winds its way to the next level with a well-built 18-pane welcoming skylight, showering the area with natural light during the day and starry skies at night.

A giant closet with four doors line one wall of the master bedroom, while two wall lamps sit on either side of the bed. The master bath has a smaller skylight plus a vanity with two sinks, a walk-in shower with dual heads plus a stackable washer-dryer.

On the opposite side of this story are two identically-sized, yet uniquely designed, bedrooms and a shared bathroom. The bathroom also has a smaller skylight plus a vanity with one sink and a tub/shower.

The third bedroom showcases wood wainscoting in an eye-catching hue of auburn-chestnut and shares the space with a large built-in desk and a queen-sized Murphy bed. This versatile room works great for students of all ages. The space also lends itself as a multi-functional room for a home office and guests.

A spiral staircase leads to another great feature – the large and private roof deck. This is a great place to enjoy al fresco dining, be it a bar-be-cue, picnic or a gourmet meal, and the prominent panorama of the Back Bay brownstones and the city’s tallest buildings.

Additional features of this home include central air, large Marvin windows and one direct access tandem parking space.

This is a professionally-managed, 100 percent owner-occupied, pet-friendly, smoke-free, five-unit building.

The home is centrally located and an easy walk to the Public Garden/Boston Common, Charles River Esplanade and Commonwealth Avenue Mall.

There are plenty of places to shop and dine, including on Newbury Street, Boylston Street, Beacon Street and in Copley Square as well as at Copley Place and the Prudential Center. The Clarendon Street Playground is also nearby. It’s also easily accessible to the Theatre District and Downtown Crossing.

Getting to the MBTA is a cinch with the close-by Arlington Street and Copley Square Green Line stations.

This abode comes with a long and fascinating history, as well.

According to Back Bay Houses (backbayhouses.org), the dwelling at 73 Marlborough St. was originally built around 1864 for shipping merchant and real estate investor John Lowell Gardner as one of nine contiguous houses.

Professor William Watson and his wife, Margaret (Fiske) Watson, bought the home in 1875 just after their wedding. William Watson had been an instructor of mathematics at Harvard University from the time of his graduation in 1857 until 1860, when he traveled to Europe to continue his studies.

According to Back Bay Houses, “While in Europe, he gathered information on the European polytechnic university model which subsequently formed the basis on which the Massachusetts Institute of Technology was organized. From 1865 through 1873, he was a professor of mechanical engineering and descriptive geometry at MIT. He later became Secretary of the American Academy of Arts and Sciences.”

By the winter of 1879-1880, this became the home of another newly-wed couple – Abbott Lawrence Lowell and his wife, Anna Parker (Lowell) Lowell. A. Lawrence Lowell was an attorney and later would become President of Harvard University.

On June 3, 1982, 73 Marlborough was purchased from Jack Fay by Sam Y. Kim. A little less than a year later, Kim converted the house into six condominium units, transforming this property into a new era of living.
