Input: Consider Input: I stayed at the millennium Knickerbocker for 3 nights while on a business trip, as it was conveniently located a few blocks away from the office I was visiting, and just about everything else for that matter. The lobby was absolutely beautiful, and the staff was beyond courteous and extremely helpful. The rooms were elegant and spacious, and I instantly felt right at home. The large flat screen TV as a nice touch and TV options were many. I headed downstairs to the bar for a drink, and was amazed at how well kept it was, as well as how nice everybody was. As this was my first time I asked the bartender about the area around and he gave me great advice about some places to check out. All in all this was a great experience, and next time I'm in the area, I will definitely be staying here. I'd recommend the Millennium Knickerbocker to anyone traveling to Chicago.

Output: positive

Input: Consider Input: Me and my husband stayed in the Allegro Hotel Chicago for 4 days 3 nights recently. We got a room with a king size bed.. Although the room is small, we got no problems with that as there was enough space for our luggages & all. However, we felt that the bed is not exactly comfortable, the bed sheets kinda feel rough to us. The walls are really thin and we could hear our neighbours talking and occasionally the flushing sound. 1 of the days, our room was not cleaned till afternoon and so we went to check with the front desk and was told that we got to request for our room to be cleaned which was a shock to us as we thought that like all hotels, rooms are cleaned except when you put on the no disturb sign. The worst is upon returning to the hotel at night, we found a bag of our garbage in the room and it was right next to our luggage. The housekeeping people must have forgotten to take it out after cleaning our bins. This is unacceptable to us. The hotel is in the theatre district and it is rather quiet at night. Although it is near the CTA trains, i would rec one to stay somewhere close to the magnificent mile where its lively at night or hotels near the chicago river so that you can get a great view. Am staying again at a Kimpton hotel in San Fran next month and i am contemplating if i should change! Overall, not a good experience and i wouldnt choose this hotel again if i were to head to Chicago again!

Output: negative

Input: Consider Input: If you're in Chicago and want to stay in The Loop, The Allegro Hotel is perfect for you. It's centrally located, stylish rooms and attentive staff. I stayed at the hotel for 3 nights and was very pleased with everything. The bed was very comfy and had plenty of fluffy pillows, large flat screen tv, radio with ipod docking station and bathroom was hip and clean. Everyone that I came in contact with was very friendly and helpful. My last day there, I ordered room service and not only was my meal perfect and delivered on time, the kitchen called to see if everything was alright. I have never had that kind of follow up service. I've stayed at the Palomar in DC, another Kimpton hotel and received exceptional service there too. I will definitely see if Kimpton has a hotel at my next destination.
