Me and my wife stayed at the Omni hotel in Chicago for a customer training at a nearby hospital. We ended up only staying for 2 nights and the service was awful here. At first once coming into the room, there was a mildewy smell in the air, which we were fortunate enough to bring a potpourri spray with us just incase. The continental breakfast each morning was terrible as well. The eggs were runny and the coffee was not hot at all. To make matters even worse, the room service attendant did not get to our rooms until the middle of the afternoon, when my wife was back from exploring the city. This was simply unacceptable by any standard.

I had requested a quiet room several weeks in advance, yet was given a room facing the street from which I could hear traffic noise. I asked to be moved and was told that nothing was available until the next day. The next morning, prior to being moved to a quiet room, the toilet in my original room overflowed creating a large unsanitary flood. About an hour later I was moved to a room which did not face the street. The room was quiet but smaller and darker. The mattresses in each room were very firm, I would even say hard. I asked if any softer mattresses were available and was told that the mattresses were all the same. At checkout I tried to give the hotel a form of payment that differed from the card the room was reserved under, and this process was still not done correctly after 10 minutes, which seemed longer because the van to the airport was waiting right outside, with other passengers. (The cost was not correctly charged until almost a week later.) As recompense for the noise, flood, etc., the hotel offered exactly nothing. Not a great stay.

I had such a horrible experience when I stayed at Omni Chicago Hotel last Saturday night. First of all, the plasma TV in my room was broken and the staff said they had no other rooms available, and they weren't particularly apologetic about it, either. Secondly, it was supposedly a non-smoking hotel, but as an ex-smoker, I can tell that people had smoked in the room recently. Additionally, the indoor swimming pool was closed due to high chlorine levels, which was really disappointing, because I was looking forward to using the pool. Finally, check-out was supposed to be at noon. At 11:15 am, the maid was knocking at the door. She asked if I would be out soon, and I thought was very quite intrusive. I will never, ever stay at that place again.
