Visited on October 26 without charging.
There are 3 parking spots with EV symbols in the hotel parking. It seems to be the same location where the Tesla chargers used to be.
On the old Chargemap pictures we see the left spot used to be a handicap spot, but now it's all marked as just EV.
The Land Rover has stickers with the hotel name, so I assume it's often occupying one of the chargers.
There is no signage about possible public access. At the entrance it says customer parking, and the stickers on the charger just contain the ad-hoc payment instructions.
Google Maps tried to take me through Inselistrasse next to Migros, but this road has been blocked off. Inselistrasse is now a cul-de-sac that must be accessed from Freimettigenstrasse just after the train crossing.
