Our first visit to Chicago and I really cannot wait to go back. The hotel was in a great location and every member of staff we had contact with were exceptionally helpful. Particular mention should go to the door staff who were amazingly helpful. The room was clean, quiet and spacious, if only every hotel were like this.
