The former single-family brownstone houses three condos, all duplexes, according to Broker Allison Mazer of Gibson Sotheby's. Unit 3 for penthouse living is for sale at a price of $3,090,000.

Living on a quiet street in a bustling city is what those living at 254 Marlborough St. in the Back Bay come home to each day.

The former single-family brownstone houses three condos, all duplexes, according to broker Allison Mazer of Gibson Sotheby’s. Unit 3 for penthouse living is for sale at a price of $3,090,000.

“There’s something very unique and special about this unit,” Mazer said.

One unique feature is the deeded elevator used exclusively by the unit’s owners. Should changes to the elevator in terms of flooring or walls want to be made, those changes are at the sole discretion of Unit 3’s owners.

Another unique feature is the unheard of condo fee in Boston of only $650 per month.

“It’s a very well run, self-managed building,” Mazer said. “That keeps the condo fees low.”

The entry has custom detailed millwork and artistic lighting as one makes their way to the elevator entry.

Three bedrooms are located on the unit’s first level, including a spacious master with an adjacent office that could also be used as a sitting area.

With a built-in window seat in the office, high ceilings and large windows, lots of natural lighting floods the room giving a bright, airy feel.

On cold days there is a beautiful wood-burning fireplace to chase away the chill or in the en suite bathroom, a large soaking tub to relax. The large bathroom also has a double vessel vanity and a shower with sea glass tiles.

Doors separate the sink area from the shower and tub area while a large closet has room for storage as well as a washer and dryer.

A second bedroom faces Marlborough Street, with its gas lighting in the evening creating a picturesque Boston scene.

It also has a wood burning fireplace, custom built-in wall shelving and a large closet with shelves for storing more clothes and shoes.

The third bedroom also faces Marlborough Street and has a good-sized closet with shelving as well.

In the hallway is a second bathroom with a tile floor and large, glass shower.

The hallway also holds another unique feature of the unit - a large wine cellar complete with a wine rack to hold multiple bottles and shelving for storing other items.

“You don’t see that a lot in city living,” Mazer said. “Plus the shelving, it’s nice to have any kind of additional storage.”

The entire upstairs floor, accessed from a wide staircase, is laid out to be the perfect space for living and entertaining with a wide-open floor plan that flows from the living room to the dining room to the large outdoor deck.

With hardwood flooring throughout, this level radiates elegance.

Because it is the top level, there are three beautiful skylights plus enormous windows and a sliding door to the deck to allow for an abundance of natural lighting.

One skylight over the living room is backlit so it glows at night, a second over the kitchen is frosted and a third over the dining area lets the sky shine through.

The grand living room holds the home’s third fireplace and has built-in shelving for showcasing books or other items as well as built-in cabinets for storage.

While there is room for a large sectional couch, the room is large enough to also hold a small table and chairs when eating in the formal dining room is not necessary.

A kitchen with granite counters, a Viking stove, Sub Zero refrigerator, pantry and cabinets galore make meal preparation and storage a breeze.

Should guests come before the meal is ready, a backlit bar and wine refrigerator allows for entertaining before heading to the formal dining room.

With room for china cabinets and more seating in addition to a formal dining table and chairs, the room also has a small granite-topped eating counter with room for two.

An extraordinary feature of the unit is the large private deck with views of the city all the way to the shining dome of the Statehouse as well as the downtown area and other buildings.

With electricity and water available, this sizeable deck creates another gorgeous area for entertaining.

Large enough for a table and chair, extra chairs for additional seating, a grill and more, three seasons of nights on the deck overlooking the surrounding area await the new homeowner.

“There are privacy shrubs and no outdoor space on one side,” Mazer said. “It’s kind of its own little oasis.”

Mazer said the Back Bay, where this unit is located, is a special area of Boston.

“It’s very residential with cobblestones and gas lit lanterns,” Mazer said. “There’s a lot of history, but it’s also quiet. It’s a really great neighborhood.”

She said being close to the Esplanade, “an incredible resource,” allows residents the opportunity to take a five-minute walk to the footbridge to access the area where runners and cyclists frequent as well as the opportunity to rent a sailboat.

According to Mazer, the price of $3,090,000 in this particular area makes the unit a great deal.

“It's a tremendous value for a penthouse home located on Marlborough Street with deeded parking, a deeded and direct access elevator and private outdoor space with incredible views,” Mazer said. “It's ready for the perfect buyer.”
