European tv runs 50 Hz vertical and (I think) 300 lines (non-interlaced)
horizontal resulting in a 15kHz horizontal oscillator frequency.
One would presume that the color-burst frequency would also be different
because it is usually some odd number of half-harmonics of the horizontal
frequency.  To convert from one to the other would seem to be very
difficult.  It would probably be simplest to take an American monitor
with you.  Neither the monitor nor the C-64 should care what the power
line frequency is, assuming you convert the voltage, because the C-64
derives the 60Hz vertical frequency not from the power line, but
by dividing down the 3.58 MHz frequency generated from an internal
crystal.
