Input: I recently stayed at the Sheraton Chicago Hotel. It was my first time staying at this hotel and, I am sorry to say, it was my last time staying there. One of my main issues with this hotel was the amount of noise. The walls must be very thin because lying in bed at night I could hear my neighbors in the next room talking. Although I could not quite make out the words of their conversations, I could definitely hear their voices as more than just a murmer. In addition, I was awakened several times by people conversing in the hallway as they walked by my door, presumably on the way to their rooms. Admittedly, I am a light sleeper, but this was ridiculous. If you decide to stay here, I suggest that you check your bill very carefully before check out. When I checked mine, I found that I was being charged a rate higher than the one that I was supposed to be charged. I had to wait in line at the front desk for someone to help me (and the front desk service is woefully slow) and finally had to ask to speak to a supervisor before the error could be corrected. Finally, though I had been told upon check-in that my room had been recently updated, I cannot believe that statement was accurate. The room appeared to be rather dated in its furnishings and decor and the carpet appeared to be somewhat worn. All in all, I round my stay at this hotel to be disappointing. Next time I will arrange to stay elsewhere.

Output:
negative
