 "But you may need nothing more than the private rooftop club with its Butterfly Bar and garden, a sunken outdoor living room with a fireplace and couches stocked with fur throws, the Masters Lounge (a trippy version of a Victorian parlor), a heated saltwater pool, and 360-degree views of the Hollywood Hills" 
 "The heated saltwater pool there is framed by Moroccan-inspired lounges, cabanas, and a bar where you can catch some of the best views in town" 
 "Large suites (most with working fireplaces and pull-out sofas, and some with kitchenettes) feature 50-inch flat-screen TVs, minibars, beds with bamboo mattresses, and loads of ornamental touches" 
 "Take in the 360° vistas of Los Angeles from the rooftop club complete with outdoor pool, fireplaces, bar, patio and garden, recognized as a hummingbird and butterfly sanctuary by the National Wildlife Federation" 
 "The hotel boasts an intimate and exclusive feel with its Private Rooftop Club, featuring gardens, a saltwater pool, indoor and outdoor lounges, a menu of Mediterranean-influenced dishes with an emphasis on exotic spices, and the Butterfly Bar, serving a "gypsy brunch" on weekends" 
 "Saltwater rooftop pool (neat!) framed by lounges, cabanas and a bar, should you need to remind yourself you're in WeHo" 
 "Guests have exclusive access to an impressive art collection lining the halls, lots of chill spaces, and the rooftop bar/butterfly sanctuary"
