I have a number of hints for this location but I am not able to find any definitive information or picture online.
The website for the hotel says there are 22kW charging stations without cable, but doesn't say anything about how many there are and how the payment works https://www.hapimag.com/en-gb/switzerland/bernese-oberland/interlaken/
In Swisscharge app, we see two plugs in roaming named "Interlaken | Höheweg 95", NLEVBEEVBP1835150*1836703 at 4kW and NLEVBEEVBP1835187*1836735 at 7kW. They appear at 2 different coordinates above the hotel.
In the M-CHARGE webapp, but not in the Android app, we can see 6x22kW connectors named "Hapimag Interlaken" and invoiced at 50ct/kWh.
I walked around the hotel but there's nothing in sight. They have an underground parking garage, this is where the chargers must be.
