Like: Picking up the car is very easy as a shuttle takes you right to the car rental area and once there, you are are your way within minutes. When dropping off the vehicle, Hertz staff were very friendly, addressed me by-name and helped me get to the return shuttle.
Dislike: What wasn't so pleasant was when I went to get the car I reserved, it wasn't available. I did get a comparable-sized vehicle, but I'd chosen one specifically for cargo space and vehicle familiarity and I wanted to feel comfortable in a car I'd driven before. Getting the car to Logan's drop-off point was straight-forward, after all the nail-biting I did to find my way through Boston!

Dislike: Hertz would not honor the total amount due at the desk, as shown on the confirmation for Easy Rent cars. They honored the daily car rate but still charged taxes and fees, even though the contract said that was to be included in the price.
