I have been to Daugavpils as an Erasmus student for a semester. I found a really quiet environment, with small classes, with welcoming classmates and helping and flexible professors. The administration offices smoothly managed documents and requests; also life in the общежитие was very fun and enjoyable.
I am a student of foreign languages, so I chose Daugavpils because of its Russian speaking minority, which makes it a pretty unique place in Europe. Still, I was negatively surprised when i found out the small amount of classes taught in Russian (evidently the main language of the inhabitants of the town). I also felt the lack of events and occasion for students to meet and mingle.
Despite all, I enjoyed my time at DU and I would really suggest the university to others and in case of international students, mostly because it is a good way to experience Eastern European culture and education.
Just to summarise: a small, quiet Easter European University!
