I am not an expert in that, but I can say for sure that even if can't find one it should not be an issue. Everyone speaks a perfect English there.
I attended Aalto University on exchange during my M.Arch. I wouldn't be too concerned about it, as English is widely used throughout the Scandinavian countries and schools. I assume this may not hold true for obscure schools in remote/small towns, but this info will be readily available if you get in touch with admissions officers directly. I would probably recommend staying in the major urban centers, and save the small spots for travel destinations.
