A penthouse with harbor views is a nice find any place. A corner unit penthouse with harbor views in the West Wing at Flagship Wharf - now that’s a tremendous treasure.

But there’s more. This residence has 2,360 square feet of living space with two bedrooms, two full bathrooms and a powder room in a beautiful boutique building with two parking spaces.

The views, of course, are center stage in every room. That the view of Boston Harbor is “grand” (in every sense of the word) is appropriate for the living room as this is a “grand” space.

Massive with three exposures, this room has a gigantic wall of windows that soars to the ceiling - a minimum of 15 feet high - plus a Palladian topper that is at least 10 feet wide.

Another exposure - a full glass pane window - is a bonus in this room that enjoys an incredible amount of natural light all year long. The sweeping view, by the way, includes the vibrant marina and Boston Harbor.

In addition to this spectacular panorama, the living room has an attractive interior view - a striking fireplace with glass doors, black granite surround and hearth. This beautiful feature is directly opposite the window wall and sits between the two niches. These two niches work well as reading nooks/mini-libraries, decorative display areas, a dry bar, etc.

French folding doors with stenciled glass inserts (these practically disappear into the archway when closed) open to a huge dining room with an almost floor-to-ceiling window wall. Dinner for eight-plus is easy in this room.

Currently, the adjacent kitchen is an attractive and functional self-contained U-shaped room. However, the change to a “contemporary look” is very doable. Take down the wall in between the two rooms, “steal” a few feet from the dining room and place the new kitchen on the back wall. The result is a stunning open kitchen-dining room where both have views overlooking the Flagship Wharf complex and the marina.

That scene continues on the lower level. Here, dark-stained, wide plank hardwood flooring juxtaposed windows that extend to the base of walls create an infinity-like effect, especially in the long corridor that separates two bedroom suites. The long hallway also insures that each large suite has maximum privacy.

In the gigantic master suite sleeping chamber, three exposures allow for memorable sights 24-7. One is a direct marina and harbor view via a full glass slider wall that opens to a Juliet balcony. This is connected to a spacious private deck (three chairs plus a table, etc. fit comfortably) with 24-inch red pavers that have access to the bedroom via a full glass pane door, perfecting exposure number two.

Exposure number three is a full glass pane window on another exterior side wall fulfilled by the position of the corner unit.

The master suite has inside bragging rights, too – such as a gigantic walk-in closet/dressing room with all kinds of custom inserts, including open shelving/cubbies, shoe racks and specialized hanging spaces.

The en suite bathroom has an extra deep soaking tub with a shower ensemble. Marble tile in the surround, on the floor and baseboards as well as the countertop are luxurious accents.

Flexibility rules in the second bedroom suite. The boudoir, which can accommodate a king-size bed, works well for guests and/or an office. This large space can do double duty - easily.

The separate laundry room is large enough for multiple uses, too. Cabinetry that includes an almost floor-to-ceiling piece and a base cabinet with a granite countertop is handy for laundry supplies and care for the full size, stackable LG washer and dryer. This large room also works well as in-unit storage for bulky items.

The en suite bathroom has a tub/shower combination with a tile surround and a vanity with complementing marble countertop. The commode is by Kohler.

Flagship Wharf is rich in amenities, inside and out. The home is surrounded by parks and marinas for year-round fun and adventure. Plenty of paved trails along the Harborwalk are great for walking and jogging. Countless restaurants and cafés dot the historic North End and Charlestown.

The Naval Shipyard, USS Constitution and Museum, and the Bunker Hill Monument are all part of the Freedom Trail that continues on to other Boston neighborhoods.

Downtown Boston and Logan Airport are just minutes away via the MBTA Ferry, which is right outside the Flagship Wharf door.

Staying “in” is pleasant, too, as the full-service building offers concierge service in the spacious and beautifully-appointed lobby, a fitness center and a resident lounge. This home also has direct-access garage with two-car parking: one reserved, self-park space and one valet spot.
