Poor sleep. We have been staying at this hotel for the past 10 years to celebrate our anniversary, However last night after we dined at Nomi and went back to our room on the 10th floor and even had a fan running on high speed. All night the ambulances and police sirens travelling west on Chicago street woke us up even until 5 am. The reviews state that the Park Hyatt hotel rooms are sound proofed, However this was not the case.
I am hoping a comment from the hotel manager.
