I followed the instructions to return the car and received a bill with no additional charges, but my credit card was repeatedly charged at midnight for two consecutive days without any explanation or invoice. I have no idea what the charges are for, and neither Hertz nor the car rental platform have responded after a week! It feels extremely risky to authorize my credit card to them! The car was in good condition, but how can this unauthorized charge issue be resolved?

The tall African American guy was very nice, providing thoughtful advice and guidance.

Overall quite satisfied, but the highway toll system in the US is a bit confusing. The lady at the counter wasn't very knowledgeable about the car, and didn't know what type of fuel to use (it's also not indicated on the fuel cap).

Although it's during the pandemic, it didn't affect the car rental service.

Like: Good service Car reserved not available, so upgraded (which actually suited us better)
Dislike: Location in Boston difficult to find
