The primary suite is a true retreat, complete with a massive walk-in California Closet and a spa-like en-suite bathroom appointed with honed Glastos stone floors and walls, a Caesarstone double vanity, frameless glass shower, deep soaking tub, and radiant heated floors. The generously sized second bedroom easily accommodates a queen-size bed and also works beautifully as a home office, guest room, or nursery.
