Visited on Monday without charging.
The AC chargers are in the underground parking. There are no gates, parking seems to be free.
The sign at the entrance says the parking is for clients and visitors, max 2h. There are signs next to the foot exits saying the parking closes with the store.
It seems like there's a single level. The chargers are not difficult to spot when driving in the one-way from the south entrance.
There's another entrance to the north, I think it's also possible to reach the chargers that way, I think you would arrive through the forbidden signs visible on my pictures.
