Erasmus in Limerick?

Hi. I'm a law student from Poland planning my erasmus exchange next year (september-january). Among my top choices is Limerick, but the more I read about the city the less convinced I am. I've read a lot about it being one of the most dangerous cities in Ireland. Is that actually true? Also I would really appreciate some insight about how the student life in Limerick looks like. How is the housing, classes at UL? Maybe some tips to getting around, meeting people, anything really would be great.
