Q: My wife and I were guests at the Hotel Allego in Chicago for a long weekend getaway (September 2 - 5, 2011). We had checked out the hotel's website long before booking and were quite excited about our trip. Once we arrived, the hotel staff informed us that the room we requested was unavailable and brought us to a different room that smelled quite moldy. When I asked to be moved to another room (my wife has asthma) we were politely told that we were unable to be switched at that time. The room was not particularly well-cleaned: we found previous guests hair in the bathroom sink and on the floor, and a film of dust across the television set. We are not the type to complain, so we went out to explore the city and assumed that would be the worst of it. At nighttime when we tried to sleep, we discovered the bed sagged terribly in the middle and the walls were so thin, every nearby conversation could be heard perfectly. We were tossing and turning half the night. In the morning we hoped a quick workout might help energize us for the day, but we discovered that the wellness and fitness center described on the website was really not at all what we anticipated: a few treadmills and a dilapidated weight rack. The concierge was almost never around in the lobby (her sign always said "Be right back!") and when we did ask her questions, she was actually somewhat cold and rude towards us. The second night was without incident, luckily, except for the terrible bed, but the third night we were woken up three times by hotel staff trying to enter the room to clean despite our "Do Not Disturb" sign. I would not recommend this hotel.

A: negative

Q: 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.

Q: went to chicago for a week in may, decided to be good to ourselves and stay in the hilton, we were not disapointed. perhaps it was becuse there were quite a few conventions going on and a lot of people were only staying 1 or 2 nights but we got upgraged to exceutive level. we had 2 double beds with a bathroom each. they beds and pillows were too die for, so so comfy ant the end of a day when we seemed to have walked for miles. all the staff were very helpful. a lot of guests seemed to ignore the staff especially the chamber maids who they seemed to think they were in their way so perhaps that why some people felt these people were rude or unhelpful. about 2 blocks away on Harrison is a cafe called "Orange" which you have to make the only place you will have breakfast, the cafe and the staff are suberb. expect a 15 min wait on a sat & sun morning.

positive
