Visited yesterday without charging.
The charger is in the outside parking lot. There are no gates.
I don't know whether the parking spots are subject to the parking meter. I'm including a picture of the parking meter tariffs in any case.
There is a parking ban posted for Friday 2024-09-13 14h-23h and Saturday 2024-09-14 09h-22h. It doesn't seem like ewz switches the live availability, it still shows available right now even though we entered the parking ban period.
