Visited on May 20 without charging.
The charger is immediately at the entrance on the left.
Parking has no gates, appear to be free.
There are signs advertising a "Wendeplatz" at the very bottom of the parking, but it's a bit of a joke. It's easier to turn around in place than trying to use their space which is just the very last parking spot in the corner crossed out. There will never be any need to use it when using the charger in any case, being so close to the entrance.
