Good.

Picking up the car was convenient, but we got a Nissan instead of the booked Mercedes. The Munich airport branch was hard to find; the GPS was not accurate. We nearly missed our flight while trying to get the correct coordinates with someone's help.

It was convenient to pick up the car following the signs at Frankfurt T1. I switched to a VW Golf DTI which was a bit more expensive but worth it. Drove up to 200 km/h, thrilling! Returning the car was a bit tricky with the GPS, easier to follow the airport signs, T1 arrival, then follow the car rental directions.

The car rental location at Munich Airport was easy to find, and the staff were professional. There was no upselling, and I even got a free upgrade on the car model, which left a good impression. The drop-off location near Munich Central Station was less impressive, mainly because there was no staff present during business hours. The office was locked, so I had to use the self-service option, which delayed me for nearly an hour while communicating with QEEQ customer service to find a parking spot.
