What is immediately above the damp patch?. If it's a bathroom / toilet or kitchen, the problem could be related to a wide range of things. At one level it could be a supply pipe which the plumber appears dismissive of, equally could it have been someone upstairs doing something silly like spilling / overflowing water which would make it a "one off" event. Am presuming timber floors and would have expected there to be some evidence of cause if water had overflowed by way of damp floorboards as the water travelled downwards. If not a bathroom or kitchen, far more likely to relate to a pipe serving the central heating system, but could of course be a water supply run on the way to another room, the location of the boiler and water tank are a bit of a clue as for instance most central heating pipes will be around the perimeter, except for an element that runs from the boiler itself.
I'd be looking for more info and the immediate question is whether the damp that has appeared is anywhere near a light fitting as it then becomes a game changer as to urgency of approach. Personally I'd be sending a clear message back to the managing agent of the flat above that the damp has not appeared of it's own accord, there is a health and safety risk and pass the problem back to them to identify the cause. It should be investigated from above, the problem will come if you find it is a bathroom or kitchen that has a solid floor covering (ceramic tiles, laminate, etc) so they've just been lazy in thinking they'd have to rip it up to look under the floorboards and see what the source is IF it relates to a leak under the floorboards. If it's stopped that points to a spillage or what would be unusual which is a leak from a waste, so will re-appear as and when say the toilet is flushed again or sink used.
Pinpointing what is immediately above the leak will give you the best idea...
