Visited today without charging.
The charger is in the underground parking. Both outside and inside parkings are behind the same gates, which were not working today. The underground area closes with the store, so the charger is not accessible 24/7.
I didn't see any payment machine in the underground area. The only one I saw was outside. But there is a sign with the tariffs that would apply if the ticket gates were working. There's 90min free parking.
