Input: I have recently stayed at the Hyatt Regency Chicago Hotel and although I have stayed there a variety of times before, for both business and pleasure, my experience this time was particularly poor. From right when I checked in to the day I left I felt like I was constantly around unfriendly people who didn't want to be at work their to do their jobs. My room was dirty the whole time even though the maid came every day, and when I was trying to sleep at night it was so loud in the hallways, I couldn't sleep. For my next visit to Chicago I won't be staying at the Hyatt Regency.

Output:
negative
