Visited on January 12 and tried charging without success.
The chargers are behind the building. There are no gates, it's accessible 24/7.
There's a gas station with a Migrolino in front of the building, very close to the chargers. Good amenities!
Despite the now-sunny weather, there was some leftover ice at the foot of the chargers which made walking around dangerous.
I wanted to charge ad-hoc, but the charge:ON website was experiencing difficulties and the page would not load. I realized I had still not created an account in the app at this time, so I tried to register, but none of the confirmation SMS ever arrived. I received them all at once 30 minutes later when I was no longer here.
