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.

The Omni Chicago Hotel was a delight to stay in. The second you step into the place, it takes your breath away. It's very modern with an antique twist. The rooms are spacious and comfortable. They are clean. Every member of the staff was courteous and polite. Proud of their place of work. Happy to be there. You don't often see that. The room service was phenomenal. Visiting Chicago was amazing, and staying at the Omni Hotel made my visit that much better. The luxurious pools were an added plus as well. I also enjoyed the gym facilities. I will definitely be staying at the Omni Hotel on my next visit.
