Set in the heart of King William, one of San Antonio's most iconic and walkable neighborhoods, 617 E Guenther Street offers a rare combination of historic presence, modern updates, and space that's hard to come by. Positioned on a double lot, this 1915 Victorian stands out not just for its architecture, but for how it lives today. Inside, the home feels open and inviting, with tall ceilings, natural light, and multiple living areas that give you flexibility whether you're hosting or just enjoying a quiet evening. The kitchen is built for both function and flow, featuring a large island, custom cabinetry, and quartz surfaces, all opening into a generous dining space. Throughout the home, you'll notice details that matter-refinished wood floors, original stained glass, plantation shutters, and three fireplaces that add depth and character without sacrificing comfort. Upstairs, the bedrooms are larger than expected for a home of this era, offering room to spread out while still maintaining the home's historic feel. Out front, the porch becomes an extension of your living space, especially in the evenings with views of the Tower of the Americas lighting up the skyline. The property itself is what truly sets this home apart. The expansive backyard, 4-car covered parking, and a detached 1,260 sq. ft. finished apartment with its own private entrance open the door to countless possibilities-guest quarters, rental income, or a private studio. There is a full bathroom in the casita which is currently behind drywall! All of this just steps away from Southtown, the River Walk, top restaurants, parks, and galleries-placing you right in the middle of everything that makes this area so special. Homes with this combination of location, lot size, and flexibility don't come around often in King William.
