A bit trouble on getting to the pick-up location without instruction, the car and service is great.

When I was booking, I was not aware that they are not at the airport. After arriving the airport, I was confused on how to get to the pick-up location. I called their customer service and nobody answered. So I used Google map, and used the sky train and walked a bit to get there. Over all, the rental price is cheaper so it's still worthy to me, but I hope that the customer can be introduced about how to get to the pick-up location smoothly when they arrive at the airport.
