Visited yesterday without charging.
This location is listed on Chargemap as having a free charger. The picture shows one charger with an attached cable. The information was last updated in July 2022.
Nowadays the charger pictured on Chargemap has been replaced. There are 3 Easee chargers with cable attached. But it seems like it's all private for Groupe E. The parking spots are all marked "Reserviert". The chargers don't have any marking except for the "Groupe E" logo.
