Timeless character in Alamo Heights. Set among mature trees and lush, thoughtfully landscaped grounds, this exceptional 4-bedroom, 4-bathroom residence captures the character and understated sophistication of Alamo Heights. Offering an enviable combination of privacy, gracious living spaces, and elevated indoor-outdoor entertaining, the property is designed for both intimate everyday living and effortless entertaining. From the moment you enter, the home's warmth and distinctive character are immediately apparent. The formal living room, anchored by a fireplace, creates an inviting setting for gatherings, while the adjoining casual dining area leads naturally into the beautifully updated chef's kitchen. Designed with both style and function in mind, the kitchen features a built-in refrigerator, dishwasher, double ovens, gas cooktop, oversized island, and breakfast bar. Beyond the kitchen, a spacious second family room opens through French doors to the expansive covered back porch, seamlessly extending the living space outdoors. 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.
