I have just seen a nice new video commissioned by Hessen state promoting Frankfurt as a study and living destination. If you want to have a whirlwind tour of the city and you are not annoyed by constant use of timelapsed video and frequent movement then you may enjoy this!
This video was part of a bigger project to showcase the region’s university’s and colleges but the benefit is if you are trying to get an idea of the region then this is a brilliant way to have a look around the various towns. It is actually quite accurate, although it makes everything look a little cleaner and happier than it really is ;-).
You can find the complete playlist of towns here.
