Excellent

The car rental companies at Sarajevo Airport are just past the parking lot, making this one easy to find. There was no attempt to upsell insurance. Sometimes not speaking English fluently can be an advantage—they might have been too lazy to engage in lengthy discussions, but they did mention everything necessary and repeatedly emphasized that in case of any incident, the first step is to call the police!

Extremely satisfied

It's okay, mainly a bit expensive.

Overall, it was a good experience. The car was quite new, and the staff at both pickup and dropoff spoke good English. The deposit of 800 euros was a bit high, perhaps because I declined their recommended full insurance. The car inspection was straightforward. After returning the car, we had a delicious Chinese meal at the Great Wall Hotel near the airport.
