Steinbourg - 16th June to 17th June 2023

Marina - 12 euros a night including electricity, you need to turn off your inverter before you turn the electricity on, will only work with the inverter off and 1 euro for 20 minutes of water.

Small supermarket, boulangerie, restaurant and chemist all walking distance from port. 

So what the sign doesn't say is that if you don't turn off your inverter, it will cause the app to crash and the whole thing doesn't apply any electricity to anybody until it reboots.
