disappointing experience
We were in the Dana in October 2012 for 5 nights. I did not manage to sleep more than 2 hours without waking up, due to the Chicago police department, but mainly because the very noisy airconditioning. On top of the noise from the outside and from the inside, sounds from other rooms on the corridor and even other floors inhibit a good sleep. The sound insulation is very poor. The rooms are nice and large, but for such a pricetag, one would expect better conditions for a good rest. If it had been possible, I would have spend the first day to look for an anlternative.
