Time Out
Zagat
Time Out "The hotel features on-site dining, a rooftop bar, a spa and fitness center"
Zagat "This "trendy" Loop spot sports a neon lightning bolt down the facade and has more of a boutique sensibility than a typical Doubletree, but still offers the trademark "warm cookie at check-in" -- though the real claim to fame is the rooftop bar, a "place to see or be seen" that has a retractable glass enclosure for year-round partying and "tremendous" views (bonus: guests at the hotel “do not have to stand in line” behind the masses for entry); “corner rooms are spacious”, spa suites have soaking tubs with views and a 24-hour fitness center overlooks the city"
