Visited on Tuesday without charging.
The charging spots are the last 2 spots before the ramp out of the underground parking, PP120 and PP119.
There are 15 minutes of free parking, then it's 1CHF for the first hour. I was there for 16 minutes indicated on the payment machine, but it gave me the free tarif anyway.
Nowhere it says the closing time for the parking. The other information contradicts each other. At the entrance it says max 3h. On the price sheet it says max 24h. It also says "special" price of 1CHF/h between 20h30 and 7h and 17h30 Saturday to 7h Monday, which is longer than 24h if the parking is closed in the meantime 🤷
The left CCS connector is broken, but shows available and being used in the live data. People like to live dangerously I guess.
