Visited yesterday without charging.
The 8 charging spots are all next to each other in sector C in level -2.
While I was there, the left plug of both AC chargers showed occupied permanently in the app. It said out of service on their screens.
The DC chargers were shown all available in the app but there was a vehicle plugged in. I didn't wake the screen to check, but I don't think they were charging (anymore?), as the LED was white. It's really annoying that this doesn't show occupied in the app because there's no way to use that charger until the person unplugs.
The building is being completely renovated, I don't know how much of the parking is involved in this remodeling. There's nothing going on in this area of the parking, but they are working on the corridor that connects the parking to the store.
The parking is open all days and around the clock, but at 3CHF/h that would be expensive night parking. It's not clear on the sign whether the first 3 free hours of parking are also offered on Sunday and at night.
