I don't mind all kids, but it's highly dependent on the children and the parents involved, and especially in anything aside from single family homes, you can't really tell what you're going to get. If it were an option, I would pay extra for an apartment in a child free building just to completely avoid the possibility of having my peace and quiet at home ruined because the building gets new tenants who let their kids run wild and make insane noise at all hours. Kids can be incredibly disruptive if they have inconsiderate parents who never tell them to behave when they act out, of which there are far too many.
