Visited on November 27 and did a short charge with M-CHARGE RFID, no issue.
The chargers are in the roof parking. There aren't any direction signs. Even the parking itself has confusing direction signs. I wasn't sure if the P/Anlieferung sign meant the parking was the first or second turn. I feel like a single symbol with 2 arrows branching out would have been cleared than 2 separate instructions ordered from closest to furthest away...
Parking seems to be free. 2.5m height limit, 3.5T limit.
The toilets are at the roof level in the staircase, so if you're only here to charge you don't even need to go down to shop level to use the toilets 😂
