The service was excellent.

Very good, they meet customer needs, and the cars are great.

No upselling, but there were too many customers, so it took an hour to get the car.

Remember to bring an international driving permit when renting a car; without it, the rental location might refuse to rent to you. It might be possible at the airport. QEEQ's customer service said the permit needs to be mailed, but you can actually do it online and just print it out.

The car pickup point at Union Square, San Francisco, likely due to its proximity to the city center, has very enthusiastic staff, but the queues are extremely long. There are self-service pickup machines nearby, but due to operational issues, their efficiency is very low.
