One thing that can be said for the owner of this Airbnb is that while they might have no idea how their apartment works, at least their communication is on point. It's not uncommon for homes to have the odd phantom light switch; we just hope these three aren't connected to anything too important — like the fridge or the oven. Perhaps the person renting this Airbnb could investigate and report back to the owner.
The lesson here is that if you're considering renting out your apartment as an Airbnb, it's probably a good idea to understand your electrics; otherwise, you might end up on a list like this!
