You need to pop key user from kwargs in PlaceEventForm.__init__() method, to prevent it from going to ModelForm.__init__() method:

views.py:

class PlaceEventFormView(CreateView):
    form_class = PlaceEventForm
    template_name = 'events/event_create.html'

    @method_decorator(login_required)
    def dispatch(self, *args, **kwargs):
        return super(PlaceEventFormView, self).dispatch(*args, **kwargs)

    def get_form_kwargs(self):
        kwargs = super(PlaceEventFormView, self).get_form_kwargs()
        kwargs.update({'place_user': self.request.user})
        return kwargs

forms.py:

class PlaceEventForm(models.ModelForm):
    class Meta:
        model = Event

    def __init__(self, *args, **kwargs):
        user = kwargs.pop('place_user')
        # now kwargs doesn't contain 'place_user', so we can safely pass it to the base class method
        super(PlaceEventForm, self).__init__(*args, **kwargs)
        self.fields['place'].queryset = Place.objects.filter(created_by=user)
