"Established more than a hundred years ago as a family estate, working horse ranch, and vineyard, the farmhouse refuge—with a black-and-white chevron-patterned ceiling installation by Joshua Tree–based woodworker Aleksandra Zee, a new Artist's Cottage, and an-on site Mediterranean-inspired restaurant, Layla—feels like a large private residence with individual dwellings, or 64 guest rooms, suites, and premium suites layered with sliding barn doors, mudcloth-style accent pillows, and club chairs. Select Premium suites feature outdoor showers, patios, and fireplaces. Lounge by the revamped outdoor pool or work up a sweat in the new fitness center with a pair of Peloton bikes. The brand new Spa at MacArthur, designed by Kes Studio (of L'Ermitage Beverly Hills), offers one-of-a-kind treatments including Sanctuary of Flowers, a 100-minute ritual combining an exfoliating body polish, full-body massage, and scalp treatment using wildflower essences concocted specifically for the spa by alchemist LotusWei." - Jennie Nunn
