I have constant, severe water hammer - loud (~60dB) vibrations in the mains pipe. They were originally started by flushing the toilet, stopping soon after but now they are constant. These vibrations do not stop when the cistern is full, nor do they stop when the valve to the toilet is closed (it is the only thing connected to this inlet, which runs from my floor to the ceiling otherwise uninterrupted, from the flat below to the flat above).

Flushing my toilet is, afaik, the only thing that started the water hammer before. I used to be able to stop it, by gently repeatedly pressing the valve in the cistern, opening and quickly closing it. It took ~1 minute of attempts to stop the water hammer. Sometimes it would flip between rattling/vibrating when I do this until it stops. It started again immediately upon flushing the toilet. However now it is stuck vibrating and nothing I can do will stop it.

When the noise was stoppable, if I disconnected the filling system (Geberit) from the hose and then reopened the valve to the toilet, the hammer started again (so it's not the filling system - it could be the bit stuck on the end of the hose?).
The valve to the toilet is full open, closing it doesn't stop vibration once it's started, fiddling around with it hasn't achieved anything so far.
My question is:
Is this problem something I can fix myself/with a plumber (e.g. with a water hammer arrestor?), or is it definitely something wrong with the building's supply (e.g. the pressure regulator to the mains pipe from the street supply?). It's definitely caused by the toilet flushing, but I can't identify anything within the toilet that's at fault.
I'm losing my mind since this has been going on for a week already and the building maintenance can't get anything done until the 3rd. If it can be fixed or at least stopped or remedied before then I really don't care how much it costs.
I've had a plumber in already who cost £90 and achieved nothing, so I'm keen to get a better idea of what the actual solution is likely to be before hiring someone else.
Let me know if there's any other tests I can perform, or pictures/videos I can provide.
