Question: I want everyone to know about the awful experience I had at the Sheraton Chicago Hotel and Towers. When we arrived at the hotel, the clerk who was checking us in said that our reservation was not in the system (I had called earlier in the day and confirmed it). After speaking to the on-duty manager we were informed that our reservation had been canceled earlier in the day and that the hotel was now completely booked. We later found out that there was a convention at the hotel and that the price for the rooms had risen dramatically. I believe they canceled our reservation just so they could make more money. I for one won't be going back to this hotel!

Answer: negative

Question: My family and I stayed here while we were visiting Chicago. This was a perfect location to many of the things we wanted to do and was easy to get around. It was in a safe neighborhood and was great accomodations. The staff was friendly and went the "extra mile" to make sure we had everything we needed. The beds were comfortable. We would definitely stay here again.

Question: I have been 4 times in Chicago, and I have stayed in 4 different Hotels: This has been for much the very best option. The lobby, the warm of the receptionist, the room, the hotel is very good. It is walking distance to the Magnificent Mile and there's no chance for you to get lost from this hotel. If you like to travel with style this could be a very good option.

Answer:
positive
