Located 3 blocks from Michigan Ave, 25 min walk to Millennium Park, across the street from Whole Foods, Flywheel, & Pure Barre. They recently freshened up the place (new mattresses, furniture, tvs). Restauant downstairs is very good, free wifi, and staff is very nice, especially the very sweet doormen, who are the same fellows I have seen over the past 5 years. I have stayed at the Dana at least 10 times, so I do recommend it--just ask for a quiet room if you go to bed early (before 11PM).
First, I am a middle-aged mom who stays at the Dana when I visit my daughter. Noise is the biggest problem for me at the Dana--it has a popular nightclub on roof which means that if your room is on one of the top floors, expect to hear the bass thumping until 2AM (although the view is nice), & the rooms don't have great sound insulation, so you might find yourself woken up by late-night revelers trying to find their way back to their rooms.
