We’ve found the epitome of refined city living in a sun-drenched penthouse duplex at 350 Columbus Avenue, Unit 6.

The distinctive, sought-after red facade endemic of South End/Back Bay architecture brings with it the location’s many (many, many) attractions, including tons of nearby restaurants, coffee shops, and local hangouts.

For anyone working in the city center, you couldn’t ask for a better homebase and for commuters, there’s the train and — sit down for this — a garage space for those needing to hop on the Pike.

Immaculately renovated, it showcases a roomy open concept living area adorned with custom finishes. The space is bathed in natural light, thanks to a bank of bay windows and a skylight. Built-in cabinetry for your books and curios and a gas fireplace serve as a warm backdrop for a quiet night in.

A granite and stainless steel kitchen has a convenient breakfast bar and breakfast nook and comes complete with pantry and washer dryer.

If being in the heart of the city isn’t enough, the penthouse’s 100 square-foot roof deck is there to bring the city lights to you. Head up the full staircase for panoramic Boston views, entertaining an intimate dinner party, or relaxing solo.

The first floor includes two generously sized en-suite bedrooms, including a primary suite with custom closets and a double vanity bath.

Recent and notable upgrades include a new hot water tank, roof, HVAC, and a fresh coat of paint throughout for a turnkey move-in experience.

The condo is on the market for $1,750,000. The sale is represented by Frank Celeste and Constance Brown at Gibson Sotheby’s International Realty, 617-872-3227.
