Input: Consider Input: The Omni Chicago really delivers on all fronts, from the spaciousness of the rooms to the helpful staff to the prized location on Michigan Avenue. While this address in Chicago requires a high level of quality, the Omni delivers. Check in for myself and a whole group of people with me was under 3 minutes, the staff had plentiful recommendations for dining and events, and the rooms are some of the largest you'll find at this price range in Chicago. Even the "standard" room has a separate living area and work desk. The fitness center has free weights, weight machines, and two rows of cardio equipment. I shared the room with 7 others and did not feel cramped in any way! All in all, a great property!

Output: positive

Input: Consider Input: We stayed at this Hotel in February 2010. The room was great we had purchased it at a raffel at work for a fund raiser for United Way. So we probably paid more then we needed but it was for charity. We were woke up at 3:00am in the morning by a group of at least 25 young people that were so loud coming off the elevators and down the hall ways they must of woke everyone up on our floor. Of course one of the rooms they rented was right next to ours. They were so loud shouting profanities and banging on the walls that we thought there was maybe a fight going on. We called the front desk who sent security up immediately. Security tried to get the people that were not registered guests to leave. We called down to the front desk two more times to send security back up again since nothing changed this went on for over an hour until it finally quieted down. Because of this we ended up over sleeping in the morning since we were so exhausted. When we complained about it in the morning managemnet would do nothing for us because as they stated we used a gift certificate. Well we still paid for it!!. They would not give us one thing free for the trouble that we had. We would never stay at this hotel again, obviously they really don't care about their guests.

Output: negative

Input: Consider Input: We loved this hotel and would definitely come back. Initially we weren't given a goldfish, which was disappointing, but then we left a tip for the housekeeper, and she rewarded us with one. We had fun sipping wine and playing Wii in the lobby every afternoon. The staff were quite friendly and helpful, even printing our boarding passes for us. Our room was very comfortable, with a cozy little alcove at the window where we read the paper. At first we were worried about noise, since our room was next to the elevator, but we hardly heard it, and didn't notice any street noise either. The hotel is colorfully and tastefully decorated, well-lit, and ideally located.
