The University of Seville has several degrees and departments. Focus on the ETSI (Escuela Técnica Superior de Ingeniería), it includes many types of enginnering degrees, but its location has a bad place in my opinion, because people need to go there by car, bus (linea C1-C2 is the unique that take you there) or bike, because ETSI is away from many places of the city.
Focusing in Aerospace Engineering (at ETSI) I could say that it could be one of the most difficult degrees in Spain, but, during the season, ETSI offers you several activities which you can participate, so you can know several things about the Aeroespace Area here in Seville.
In contrast, I would like to tell that Seville is a beautiful city and if you study here you really fall in love with the city and its residents.
