I absolutely love this hotel! Every time I fly internationally out of Chicago O’Hare, Staybridge is always my go-to place to stay before my flight. The hotel itself is wonderful, but what really keeps me coming back is the staff. I usually arrive at night, so I deal mostly with the night staff, and they are absolutely amazing. They are always friendly, welcoming, professional, and helpful. There honestly are not enough words in the English language to describe how great the staff has been every time I stay here. The rooms are always spotless and extremely comfortable. The showers are nice and hot, the beds are comfortable, and I always get a great night of sleep before heading to the airport. After a long drive to Chicago or while preparing for an international trip, that peace and comfort means a lot. I also love the bar and the overall atmosphere of the hotel. It is relaxing, convenient, clean, and consistently gives me a great experience. I travel quite a bit, and when I’m flying out of O’Hare, I already know where I’m staying. This hotel has earned my loyalty. Amazing staff, beautiful clean rooms, great service, and a comfortable stay every single time. I highly recommend it!

Great location, staff and amenities. The room I had was small yet fit my budget and had everything I needed. My only suggestion is to have 4 chairs per table in the breakfast/bar area.
