This 14-story boutique hotel deftly manages to straddle the line between fun and conservative. The stylish decor is a fresh alternative to Chicago's many cookie-cutter business hotels: The rooms feature dramatic deep-red headboards and green-striped walls, while the lobby -- with its gold decorative accents and zebra-striped chairs -- looks like a 1930s-era salon. Despite the funky feel, the Monaco is rather subdued; it's a place to relax, not pose. The eclectic furniture includes mahogany writing desks and ergonomic chairs; suites come with a two-person whirlpool spa and pull-out queen-size sofa bed. (If you're taller than average, you can request a Tall Room, with longer beds.) All rooms include \"meditation stations\" -- comfy seats tucked into the larger-than-average windows, which are perfect for taking in the cityscape outside (ask for a river view). Along with its sister hotels -- the Burnham and the Allegro -- the Monaco also offers an in-room yoga program and offers special packages for visitors traveling with pets. Given the hotel's playful spirit, it attracts a younger clientele, with an overall vibe that is laid-back and friendly rather than so-hip-it-hurts (this is Chicago, after all, not New York).
