637 Valley Road Your Private 7-Acre Summer Resort on the Silvermine River - Trade the ordinary for an extraordinary summer at 637 Valley Road, a sprawling 12, 000-square-foot stone estate where "vacation mode" is the only setting. Whether you're perfecting your serve on the private tennis court, hosting legendary poolside barbecues on the bluestone patios, or winding down with s'mores at the oversized fire pit, this 7-acre park-like playground is built for sun-drenched memories. Inside, the luxury is just as effortless, featuring eight cozy fireplaces for cool riverfront evenings, a billiards room for rainy-day tournaments, and a sleek chef's kitchen ready for farm-to-table feasts. With a separate guest wing and a charming detached cottage, you'll have plenty of room to host the whole crew. Located just minutes from the Long Island Sound and the train, this is more than a rental-it's your own private country club for the season.
