If you are not from Chicago and you are flying in from out of town...
You can fly into O'hare airport or Midway airport. They are the same distance to downtown Chicago.
If you fly into Midway, there is the Orange line el available to downtown. From Ohare is the Blue line el.
The salon is .5 miles from the Blue line el Damen stop.
The best place to stay is at any hotel in downtown Chicago (I recommend using Hotwire.com).
A cab fare to the salon is approximately $15.
