Overall, it was a pretty good experience.

Very satisfied

The staff were very patient

Unfortunately the vehicle that I originally booked was not available. I was offered a vehicle in the same class, but that was a matter of opinion, as I was unable to get all my bags in. After going all the way back to the desk to complain, I was offered a suitable vehicle that would fit my needs.

Like: Clean car, matched the size we had ordered although not the brand. Easy to collect (after the long queue) and drop off at Munich railway station although you need to keep your eyes peeled to find the drop off garage.
Dislike: We queued for nearly an hour at Munich airport to pick up the vehicle even with the ticket system. The ticket machine needs to be more obvious or at least a more obvious sign.
