The oversized guest suite features custom closets, a beautifully updated bath, and a separate flex room ideal as a home office, fitness room, or private retreat. The primary suite overlooks the lagoon and features exposed wood beam ceilings, dual custom walk-in closets, and a spa-inspired bath complete with a freestanding soaking tub, oversized shower, and expansive dual vanity. An upstairs laundry room and additional built-in storage add everyday convenience.
