Uppsala itself is a great city, it’s easy to go to Stockholm and Arlanda.
But to be in Uppsala as a university student is a whole experience on its own. With Nations, parties, fikas, cafés, parties (yes again), bars, knitting groups and many other events Uppsala has a place for everyone.
(The other Universities in the top 3 would be Lund University and…… well the third is not set in stone as there are a few universities and “högskolor” to choose from”
In my experience professors and teachers, competence will vary depending. But the great ones are really great.
