Tucked away on the fifth floor of the former Charlesgate Hotel at the intersection of Charlesgate East and Marlborough Street in the Back Bay, Unit 506 has views of the Charles River and the Cambridge skyline from almost every room.

Urban living is exciting - period. Residential options are endless and each one is unique. Take this open-concept, single-level home with iconic Boston views in a historic building (with an elevator). The location is incredible, too. Talk about an urban win-win…

Tucked away on the fifth floor of the former Charlesgate Hotel at the intersection of Charlesgate East and Marlborough Street in the Back Bay, Unit 506 has views of the Charles River and the Cambridge skyline from almost every room. With three large bedrooms, three full bathrooms and 2,139 square feet of living space, this corner unit is listed by Julie Harrison and Mary Conner of Gibson Sotheby’s International Realty for $2,450,000.

What you see outside is fantastic, but what you see inside is incredible.

On their own, two large three-window bays are immediate focal points in the fully open concept living-dining room and kitchen. But the curved one-over-one windows with detailed casings make these architectural features as outstanding as the view that includes the legendary Citgo sign in Kenmore Square. As each bay is extra-wide, flexibility rules when deciding how to use the space. Slightly divided by a slim wall, one of these alcoves has ledges to accommodate books and décor.

A large fireplace with a brick surround and a classically detailed mantel at one side of the room is indoor eye candy. A candle chandelier hangs over a dining area that can accommodate seating for six or more people. On the opposite side is a spacious living area that allows for various furniture configurations.

Overlooking the living-dining area is a gorgeous kitchen. U-shaped with an extra-wide peninsula that seats three people (and can double as a server for formal/casual dinners), the kitchen also has a substantial amount of white cabinetry. Stainless steel appliances that include a Bosch dishwasher, microwave and four-burner electric range sparkle against the black granite countertop.

A more intimate space adjacent to the open living area has multiple uses, too. Setting up this “room” with a view – another one-over-one window overlooks the Charles, too – as a den/study or a mini media center are viable options. On the other hand, making this a sitting room as an extension of the living area is another possibility.

Although the nearby full bathroom is thoroughly modern with a deep tub/shower combination and tile surround with a product niche, the marble tile floor in a basketweave pattern gives this loo a classic touch. The Toto pedestal sink and linen closet with a mini French door address all things practical.

The adjacent storage closet is an urban dream – a long walk-in affair that holds an enormous amount of stuff - bulky and/or otherwise.

The primary suite, which is in a separate wing – so to speak – at one end of the unit and well away from the main living area, is a retreat in every sense of the word. An extra-wide three-window bay in the expansive sleeping chamber includes the memorable view of the Charles River and Cambridge. An alcove, complete with a one-over-one window, can be used as a mini gym, an office or a cozy sitting room.

The deep walk-in closet, which is lighted, has an abundance of custom inserts: open shelving, cubbies, dedicated hanging spaces, etc.

In the two-section en suite bathroom, a pocket door allows for personal privacy. The vanity is in one section; the commode and step-in shower in the other. Oversized and fully tiled, the shower also has a built-in bench.

Using the second bedroom for guests may or may not be a good idea – depending on how long you enjoy the company. From the pocket doors with etched glass panes with a decidedly Art Deco feel to an extraordinarily wide three-window bay, this room exudes such warmth and charm that wanting to linger is inevitable.

The fireplace with a brick surround and a mantel with classic carvings and the view of the Charles and Cambridge only enhance the inviting ambiance.

The room is large enough for a desk or a cozy seating area.

A third large bedroom (or office) at the end of a corridor behind the kitchen can be guest quarters, too. A lighted double closet works for clothes, office paraphernalia and/or storage while a wide curved arch that showcases the huge three-window bay adds instant character. The Brazilian cherry floor, which is a contemporary element, is instant elegance.

Laundry facilities that include a full-size stackable Bosch washer and dryer are in this area, too.

Looks and location aren’t the only perks that come with this home. Residents have access to a beautiful common patio and an amazing roof deck with 360-degree views. Garage parking is also available.

A little building history

The “sumptuous” lobby area at 4 Charlesgate with its ornamental tile and mosaic work reflects the 19th century grandeur of the former Charlesgate Hotel that is now home to luxurious condominiums. The hotel that catered to an exclusive clientele has faded into Boston history, but the common area remains, greeting residents and guests whenever they enter the building.

The stately Romanesque Revival style, brick and Indiana limestone hostelry is adjacent to the Barnes Mansion – another condo complex. Both were built at the end of the 19th century. Rotch and Tilden were the architects for the Barnes family and John Pickering Putnam was the architect for the hotel.

Putnam later bought the Barnes mansion, which the owners had never occupied. In 1996, after various uses including a stint as a female dormitory for Boston University students, the two buildings became two separate condominium complexes: the Barnes Mansion at 10 Charlesgate and the Charlesgate at 4 Charlesgate.
