The Peninsula Beverly Hills

Consistently rated among the best hotels in the country, The Peninsula Beverly Hills earns it partly on the strength of its rooftop spa and garden pool — a sun-drenched, impeccably maintained escape that feels worlds away from the bustle below. The spa's own photography shows a Himalayan salt sauna, though the written facilities list doesn't name it — confirm before booking if the sauna is the point. The thermal suite is as polished as everything else here, which is to say flawless. Service is the Peninsula's calling card: anticipatory, gracious, never stiff. Rooms are spacious and classic, with private terraces on many. It's old-school five-star done about as well as it gets in LA, and the rooftop is the kind of place you'll struggle to leave. Spa access for guests may carry a fee or require a booking for the full thermal suite, so confirm the details — but the pool deck alone is worth the stay.
