"Hyper-stylish and bathed in natural light and textures, most rooms in the 26-story high-rise have floor-to-ceiling windows lasciviously exposed (should you opt not to use the blackout curtains) to neighboring offices and condos. The vibe is simultaneously spare and plush, with industrial-cement ceilings, ribbed wallpaper, indecently comfortable beds, and metallic velour textiles. All rooms have spa-inspired bathrooms and the latest gadgetry, including fully stocked wine chillers. The spa, booked solid on weekends, has a greatest hits menu of moderately priced massages, facials, and wraps. The Dana has a choice location between North Michigan Avenue and the River North dining and gallery district, but reserve a table if you want to go to its duplex steak and sushi restaurant, Aja, a neighborhood hot spot. The rooftop Vertigo Sky Lounge has a glassed-in bar and an outdoor fire pit where the city’s remaining smokers can light up with impunity."
