I studied my Bachelor in Business Management at Universitat Pompeu Fabra and I liked it a lot!
I think UPF is one of the best universities in Barcelona, mainly for Economic studies for many reasons:
First of all, the first years you get a good basis of the field you are studying (for example, I was studying Management but I had also the basis of Economics) and after you specialize in what you prefer. I think this is really good because having a good basis enables you to understand more and have bigger knowledge.
Also, it is an international university, since there are lots of Erasmus students and therefore, many classes in English.
Moreover, the teachers are really good, they have the best Curriculum you can imagine!
And also, the university gives lots of opportunities to students to find a good company where to do your internship, a good university where to do your Erasmus and even they try to help you looking for a job after your studies!
In general, I think you learn a lot in UPF and it gives you lots of opportunities to learn and improve!
