Visited on January 25 and charged with credit card, no issue.
At idle, the charger was advertising max 132kW on both connectors. Once charging at 62kW, the second connector was still advertised as 111kW. Both values seem a bit strange. It's supposed to advertise 150kW per connector, 200kW combined under ideal circumstances.
The toilets are accessed from outside on the left side of the building. You need to ask inside for unlocking.
