So this is a bit of a random post, but maybe someone who needs it might find it on Google.
There is no obvious signage, or documentation when hiring from Europcar as to where exactly to return your car when you’re dropping it off.
I’m sure if we’d picked up our car from Mulhouse train station, it would have been from the same place as dropoff, but we didn’t- we picked up our car in Basel so consequently had zero clue where to leave the car.
The dropoff point is actually in the long term carpark, known as Gare Centrale Parking. As I said, there is no signage for this at all.
I’m glad we allowed plenty of time for our car drop off this morning or we may have missed out train to Paris!
