The local car rental company I used was quite good.

The shuttle service right at the airport entrance is extremely convenient, and there is a drop-off service to the airport. The service is truly excellent. The provided studded snow tires ensured no slipping throughout the trip, whether on snowy, rainy, or regular roads. Very safe. It was my first time driving a hybrid car, and since I couldn't hear the engine, I thought the car hadn't started. The staff ended up laughing at me for that.

Returning the car was fairly quick, but the airport shuttle runs every 20 minutes, so make sure to allow enough time.

No issues with the booking, car was exactly as expected and there were no hidden fees. For a car rental company with an off-airport pickup site, it was very easy to get to and from the airport. My car battery died on the first day and they were very helpful with getting it serviced and reimbursed me for the fee I paid.
