Visited on November 2 and charged with credit card without issue.
The parking spaces were not yet painted. The left spot was really confusing, it had the "KUNDEN SOCAR" text on the ground like the others, but also a parking sign forbidden except "Fofo taxi". I had to use that spot to charge when I arrived as the other one was already occupied.
The car next to me was pulling 80kW before I plugged in, then it dropped to 70kW, but I'm unsure if that was charger or car limited. The max I saw was 70+54kW, so we were not maxing out the advertised 150kW.
The toilets are inside and don't require a code. There's no way to see whether the door is locked. If you can't open it, it probably means it's occupied.
