Which area should I look for accommodation

I am looking for accommodation and I believe that it might be difficult to get accommodation in Paderborn, and I have read people say that to look in places like Lippstadt or Hamm but aren't those places a little far away? according to google maps it takes atleast an hour to reach the University. Can you tell me if this is wrong and you can reach their faster or can you tell me some other place that I should look for accommodations.
