Visited on July 5 and did a short charge with AVIA Volt RFID.
One space designated for public charging, with QR for 90054.
The signage regarding the non-charging spaces isn't super clear. On the other side of the road there are many more "Besucher" signs, but on this side there is only 1 or 2, and they are perfectly aligned with specific charging spaces, leaving you wondering if it applies to the entire row, or just those specific spaces. Since the charger is by Share Birrer, I imagine it's public for everyone and not just the visitors of the houses.
