 "The difference: this one's downtown, near the bar-filled East Village and media-mecca Flatiron" 
 "Occupying the former 1911 Beaux-Arts Guardian Life building, it offers recreation and nightlife, beginning with a cozy and hip underground bar and eclectic music scene" 
 "Choose to stay in and there's Todd English's Olives, a buzzy lobby lounge, and the Gerber Group's sexy Lilium nightclub in the basement, with ace DJ talent" 
 "The adjacent bar is a ruckus from 5 pm on any day of the week (craft beers, small-batch spirits, and champers fuel the fun), and the adjoining lounge—the Living Room in W-speak—houses what has become W Hotels' trademark game area, with checkers, chess, backgammon and even a few books" 
 "Unusual for a hotel bar, the Living Room draws a healthy lot of locals: the Midtown crowd loves to stop by after work to lounge on the cushy couches and throw back cocktails made with freshly squeezed juices"
