I was very impressed with everyone I had contact with at ACE rent a car at Ohare airport. Everyone was very courteous and went the extra mile to serve. When I returned the car, my GPS got me lost. I kept calling for directions (3 times). Each person I spoke with was patient and trying hard to help me. The third time I called, the woman stayed on the phone with me until I made it to their business. I was so grateful for their kindness to serve and to help!! Most unusual for a car rental co!
