Just saw it this morning, the upstairs neighbour must have forgotten to close the tap or something, because a lot of water is falling from the ceiling. I went to his flat, but he's at work. Asked other neighbours, but don't know his name or number.
Have texted my landlord to tell him as well, but what else can I do?
Should I stay or should I go out as normal? Is there anybody that can be called, such as an emergency service or something?
