The fully equipped gourmet kitchen features granite countertops, a large island, elegant slate flooring, stainless steel appliances including dishwasher and washer/dryer. A soaring cathedral-ceilinged living area framed by a wall of windows showcases a spectacular lake view, bringing the outdoors in and opening onto the deck. Warm hardwood floors and a modern Swedish wood stove create a cozy gathering space in every season. The main floor presents a full guest bath and a gorgeous primary suite with full bath; second floor features three generously sized bedrooms plus full bath. A separate queen-sized bedroom cottage sits steps from the shower and hot tub.
