Visited on July 5 and did a short charge with eCarUp app.
The parking is accessible without gate. It's a paid parking, but there's also a very small ban sign I almost didn't see at the entrance that forbids "unauthorized people" from parking here, with seemingly no mention of what is a legitimate parking reason. Also, how does this kind of authorization work since you may only park with payment, but payment is only accepted during weekdays. Parking any other time cannot leave any official trace... There's no text saying to print a blank ticket for the free parking periods, and I don't know whether the meter would provide one.
In the eCarUp app, the markers are arranged in a row, that makes it seem like the chargers are from left to right:
ZPR301510
ZPR301239
ZPR301140
ZPR301136
ZPR301118
ZPR301093
ZPR301026
But this doesn't match with reality. This is the true order, left to right:
ZPR301140
ZPR301118
ZPR301239
ZPR301093
ZPR301510
ZPR301136
ZPR301026
ZPR301135
The first 2 chargers don't have EV symbols on the ground. The next 4 have EV symbols. The last 2 are behind Mobility parking spaces. The very last charger is not visible in the eCarUp app at all, but it has the QR code like the others and can be accessed that way (but it's one of the Mobility ones so no reason to ever use it)
