Please don't laugh (too much), but maybe someone can tell if this is safe or not? It looks at best a total bodge job to me, and at worst downright dangerous, but I don't know what I'm on about to be honest.
My wife and I live in a pretty old building, not especially well maintained, and have been feeling very mild electric shocks from our bathroom sink. We called in an electrician (friend of a friend, but still a pro… apparently) to check it out. He said the problem probably wasn't originating in our apartment, but he couldn't know for sure without ripping the walls down. He did this (see images), and said it's a safe temporary solution. His idea, as far as I understood, was to ground the sink to the back of the washing machine.
I guess I should call in an actual pro right? Any advice would be much appreciated.

No! That's not safe at all. Please disconnect power to the application at the panel and call for a qualified and licensed electrician to sort this out.
I'm especially concerned by the routing of the dubious ground wire along the edge of what looks like your shower. If that gets "HOT" due to some fault and you drip some water, it may be lethal!
