About This Home
Martin Acres gem with Flatiron views! Love where you live in this ideally located Martin Acres home where the Flatirons steal the show and convenience is second to none. Step inside and find an easy open flow between the living, dining, and kitchen areas. A rare wood-burning fireplace adds warmth and character while the bay window in the dining room perfectly frames those iconic mountain views. The kitchen shines with newer appliances and a stylish backsplash, ideal for casual mornings or entertaining friends. On the main level you will find three comfortable bedrooms, including a primary suite enhanced with updated lighting and a private bathroom. Downstairs, the spacious finished basement is a true bonus for movie nights, a game room, or space for guests. The second wood-burning fireplace adds cozy charm while two additional non-conforming bedrooms expand your options for a home office or studio. Recent updates include new gutters and a new basement escape window about three years old, offering peace of mind. Outside, a mature tree provides a shady retreat in the private backyard, perfect for quiet afternoons or casual gatherings. You will love the ease of getting around with Table Mesa shopping, dining, and transit just minutes away and a lovely neighborhood park an easy stroll from your front door. This is a rare opportunity in sought-after Martin Acres, a home with great bones, an unbeatable location, and that easy South Boulder lifestyle everyone is after. Experience the views, embrace the lifestyle, and make this Martin Acres gem your own!
