The thoughtful floor plan also offers a private guest suite on the main level, complete with a full bath-an ideal retreat for overnight guests or flexible living arrangements. The oversized primary suite is a true sanctuary, filled with natural light and designed for relaxation. The beautifully renovated primary bath elevates the experience with dual vanities, custom built-in storage, a generous walk-in shower, and an impressive custom walk-in closet. Upstairs, two additional bedrooms, two full bathrooms, and a generous game room provide exceptional flexibility for family and guests, while preserving the home's distinctive charm and sense of scale. The outdoor living spaces are where this residence truly shines. A generous covered porch and oversized patio overlook a stunning Keith Zars pool framed by mature landscaping, creating a private, resort-inspired setting for leisurely afternoons, entertaining, and al fresco dining. The grounds offer the rare combination of beauty, privacy, and effortless livability that defines exceptional Alamo Heights living. Adding remarkable versatility, the guest quarters above the garage offer approximately 576 square feet of additional living space, including a living/bedroom area and full bathroom. Ideal for guests, a private office, studio, homeschool space, or extended family, this separate living area provides flexibility without compromising the privacy of the main residence. An oversized two-car garage provides abundant storage, while every aspect of the property reflects a thoughtful balance of comfort and functionality. Beautifully situated in one of San Antonio's most coveted neighborhoods, this is a residence that offers not simply a home, but a refined Alamo Heights lifestyle-private, gracious, and designed for exceptional living.
