I’m familiar with their Otaniemi campus, as I used to frequent it a few years ago, before it was actually called Aalto University. I’m not at all familiar with the design courses however. Only thing I know, is that the universities that formed Aalto were some of the highest rated in Finland.
do not have specific information as well as i did not study there but as i have read many papers coming from professors from Aalto (and from what i see online etc etc) it must be pretty good school.
i think if i was again a student i would consider it.
