I charged again while staying at the Inn this week.
I don't think there has been any change. I stayed at the Inn earlier this year as well but didn't charge then.
Sometime after my stay in 2023 the parking spaces have been made paid. You need to reserve your parking spot on the website and park on the exact number you booked. The charging "spot" is not part of the numbered spots, you can park along the wall for free during the charge.
The charger doesn't appear to have a "connected" status like most stations on eCarUp. The app doesn't show anything after you plug in, you have to start the charge directly from the "available" state. And when the charge ends, it reverts to "available", despite the car still being plugged in. This last part is the most annoying, as you won't really know if the charger is free by looking at the app.
