Car was as expected, but the services from Budget was poor.

Renting a car in the US is really convenient. Upon landing, a shuttle bus takes you to the car rental lot. You present your driver's license, international driving permit, and passport, authorize a pre-payment, and they tell you the parking spot. When you find the spot, the car keys are already there waiting for you. Just drive away. Returning the car is even easier. Drive to their parking lot, and an employee uses a device to inspect the car, then provides an invoice. In less than a minute, you're done. We even changed the return location twice during the trip, and they agreed without any hassle. Highly recommended.

I don't understand why I was charged an extra $39.85 at the end.

Satisfied

When I picked up the car, it was snowing heavily in Boston, and there was no one at the reception area. The attendant was very patient with me. Since I had to return the car early in the morning, the attendant patiently called to check if self-service return was possible. Due to an issue with the insurance on my order, it took a long time, and I ended up changing to an order with insurance. The entire car rental process took nearly half an hour, but the attendant was not annoyed. Considering that I was driving to Richmond, he offered me a larger car and repeatedly reminded me to be careful because of the snowy conditions in Boston. (Indeed, the roads were very slippery that day, and I could only drive at less than 10 km/h. Even slight acceleration made the wheels slip, but the roads were much better the next day.)

The car was ok but the tariff didn’t match with the one on the app it was more expensive at the moment of pick up

The app was great
