Nestled on nearly three acres of private mountain serenity, 5508 Old Stage Road offers the perfect balance of seclusion and convenience-just five minutes from North Boulder's favorite coffee shops and restaurants. This beautifully updated four-bedroom, four-bathroom home spans 3,332 square feet, blending modern comfort with the tranquility of nature. This layout has you fully covered with two main-level secondary bedrooms, one with an en-suite bathroom, the other with a convenient hall bathroom. Upstairs is a private owner's retreat, with a comfortable bedroom, en-suite bathroom, and massive walk-in closet. Just adjacent is a useful flex space for your quiet work-from-home or mediation room (with its own balcony!). Downstairs in the walkout level, the potential is unlimited: another bedroom and bath create the private guest suite; the flex space could be a playroom or media space; the second den has sliding doors to access your mountain retreat; and the amount of storage space is unbelievable. Step outside and immerse yourself in the epic and iconic cycling routes that Boulder riders dream of, or access North Sky Trail via Hogback Ridge right from your back door for endless hiking and exploration. Whether you're savoring the peaceful surroundings or taking in the breathtaking views, this home is designed for those who crave both adventure and relaxation. With its unbeatable location, thoughtful updates, and seamless access to world-class outdoor recreation, this is the ultimate close-in mountain retreat-a rare opportunity to live the Boulder lifestyle without compromise.
