Combining exceptional amenities, an unbeatable location, sophisticated style, and generous living space, 135 Sheridan Street #404 represents a rare offering in Portland's condominium market--a one-of-a-kind residence in the heart of the coveted East End. Created through the seamless combination of two units, this penthouse corner unit offers over 2,300 square feet of thoughtfully designed single-level living. The home features four bedrooms, two full baths, and one half bath, with an open layout that lives even larger thanks to soaring ceilings and sweeping views of the city skyline and Back Cove. South-facing windows flood the interior with natural light year-round, while two private decks extend the living space outdoors, creating a bright, airy atmosphere perfect for everyday living and entertaining. Situated on a quiet residential street, the building is steps from everything that makes Portland's East End one of Maine's most desirable neighborhoods. Acclaimed restaurants, bars, coffee shops, bakeries, breweries, distilleries, music and theater venues, parks, the Eastern Prom, Portland Trails, and the waterfront are all within easy walking distance. Professionally managed and meticulously maintained, the building offers true low-maintenance living. The property includes an unheard-of three deeded parking spaces--two in the attached heated garage and one surface space directly adjacent to the building. Additional features include efficient natural gas heat, central air conditioning, and a gas fireplace. Recent improvements include a renovated primary bathroom with heated tile floors and a curbless walk-in shower and custom built-ins throughout for your library, art, and collectibles. Also includes two large secure storage units to keep your living area clutter free. Offering an extraordinary combination of size, location, views, parking, and amenities, 135 Sheridan Street #404 is a unicorn in Portland's premier East End neighborhood.
