Although the University of Sevilla is spread in the city, I will talk about my experience at ETSI.
The classes are really theoretical and normally teachers have old methods (this doesn’t apply to the specific aerospace subjects) but on the other side, several clubs can be found on the university where soft and hard skills can also be developed and also some sports teams that even compete in EAGs at Toulouse every year.
The library is really nice, although it gets full early.
Social life around this specific campus is 0 but using only one bus line you can get to other campuses as Viapol plenty of bars and students.
Where to live? everywhere near to lines C1 or C2 are recommended, although Macarena or Triana are the most popular neighbourhoods.
