Input: Consider Input: My first trip back to Chicago in about 7 years was perfect! I chose the Knickerbocker as I had read that their rooms were recently renovated on top of being a great location to Michigan Avenue, Rush Street and downtown Chicago. I must say I was very impressed with the guestrooms! I had not stayed there prior but it definitely is a refresh from what I've seen in photo's posted on the reviews. The guestrooms are nicely decorated with a modern feel and they are good sized for a historical hotel! The beds are wonderful -- I need to get a pillow top mattress at home! I used the Internet access with no issue and I LOVED the larger screen TV's. The shower is fun with the different types of shower heads you can choose. And the bathrooms are fresh with all new granite and tile. I'm anxious to get back to Chicago and it won't be 7 years from now! I would highly recommend this hotel -- fantastic guestrooms, location and staff! I've added some digital pictures of my room as they are completely different from the one's I saw on previous reviews with the new renovation.

Output: positive

Input: Consider Input: I booked my room at the Sheraton Chicago Hotel and Towers somewhat reluctantly; I was not enthusiastic about spending over $200 on this room after seeing the lackluster photos on their website. I was pleasantly surprised when I arrived that the lobby did not look as stuffy as it did online. Unfortunately, my hopes were dashed once again when I arrived at my room. I say 'at' because after discovering my newly issued key was not working, I had to wait ten minutes before someone finally came to let me in. The room was painfully small-- if I didn't know better I would have thought I was staying at a Red Roof Inn! The "sweet sleeper bed" had stiff and scratchy sheets, with a cheap-motel-thin coverlet. The disappointment continued after I entered the bathroom and found that it not only reeked of smoke, but also outfitted with the cheapest trimmings possible. I stayed my two nights, and was surprised to find out that all sorts of other charges were added to my room (for which I was not responsible), charged on demand movies, an empty mini bar, AND for smoking in the bathroom. HAH! I have stopped payment on my credit card, and most certainly will not be submitting myself to this horrific experience again.

Output: negative

Input: Consider Input: Just back from a business trip. The Homewood is in a great location just off the Magnificent Mile, includes a great breakfast, heavy hors d'ouevres for dinner with beer and all for a pre-paid rate of $129. Without a doubt the best value in Chicago for a long, long time.
Output: positive
