331 Main Street TWO HOMES, ONE DREAM PROPERTY IN THE BAY ST. LOUIS HISTORIC DISTRICT! Picture this: coffee on the screened porch, a stroll three blocks to the beach and marina, then an afternoon by your own in-ground pool. This Historic District gem pairs a 2, 260 sq. ft. main home with a charming 1, 208 sq. ft. guest cottage, for 5 bedrooms, 4 full baths, a sunroom and plenty of room to spread out. Each home runs independently with its own entrance and parking, and the lot stretches from Main St. through to State St. The cottage is a natural fit for an Airbnb or VRBO short-term rental. Visitors love staying in walkable Old Town near the beach, restaurants, shops and festivals. Want to keep it in the family? It's a great setup for multigenerational living, in-laws, or long-term rental income. Private patios, lush gardens and small-town coastal charm complete the picture. Homes like this rarely come along, so schedule your showing today!
