98 Caselli Avenue delivers the rare combination of location, scale, charm, and flexibility – all in the heart of the Castro. Perched on a quiet street at the top of this vibrant neighborhood, this modern 1,760-square-foot home spans two levels of thoughtfully permitted space. The main level offers two bedrooms and an updated split full bath, along with a spacious family room that opens to a large walk-out sun deck – ideal for indoor-outdoor living. The adjoining modern kitchen features abundant cabinetry and stone tile floors, blending function with style. Common area interior stairs connect to the lower level, where you’ll find a third bedroom, a second updated bath, media room, and storage. With a separate entrance on Clover Street and washer/dryer hook-ups (in addition to the main-level in-unit laundry), this level offers exceptional versatility – perfect for extended family, guests, roommates, or flexible work-from-home living. Period charm shines throughout with hardwood floors featuring inlays, coved ten-foot ceilings on the main level, picture rails, and classic wainscoting – timeless details that add warmth and character. Plus modern updates including Andersen double-paned windows throughout. Part of a two-unit HOA. While peacefully tucked away, the home is just moments from the energy of the Castro’s celebrated restaurants, boutiques, and nightlife. Nearby green spaces include Kite Hill, Seward Mini Park, and the Eureka Valley Recreation Center with dog park and tennis courts. Walk Score: 90.
