Hi Daniel,
I'm actually from Logroño. I've studied in that University too.
I met some foreign students some years ago and I can tell you they were quite happy about being there.
Logroño is a small and quiet town, there's always nice people around and it's easy to deal with other students.
There are fiestas at University and special days (Thursday night normally) in town (bars...) especially for students.
I also think it's a good place to learn Spanish. Well, if you have any question, just tell me.
When are you coming?
