*** Multiple offers - best and final due Monday (5/4) by 5 PM *** This elegant Colonial presents a refined blend of comfort, spaciousness, and timeless design, enhanced by major upgrades in recent years including a newer roof, windows, HVAC system, and hot water tank. Hardwood floors flow throughout, leading to a eat-in kitchen that opens seamlessly into an inviting family room anchored by a classic fireplace. Sliding doors extend the living space to a three-season screened porch overlooking a deep, level, park-like backyard. A flexible first-floor study offers the ideal space for a home office or quiet retreat, while the upper-level features four generously sized bedrooms and two full baths, including a primary suite with a tiled ensuite and dual closets. The lower-level basement area is designed for entertaining, offering ample space for a home theater setup, a refreshment area with refrigerator and bathroom, and the added luxury of a private sauna -- conveniently connected to the two-car garage. Ideally located near major roadways and shopping, and within the highly regarded Niskayuna School District, this impeccably maintained home is truly move-in ready.
