Where to live in Denver!?

I just got accepted to Regis University for fall 2009 BSN program. I have never been there, but hear it's an amazing city. I was wondering if anyone could give me some recommendations on where to live. I will be moving with my boyfriend and dog. We'd like to find a house or townhome with 2 bedrooms, and if possible with a yard, but don't want to spend more then 800 a month. With our dog, who is only 7mos but will probably get up to 100lbs, we worry about being an apartment, he's loud when he runs around! What areas are good/safe to live? That are still relatively close to Regis? I wouldn't mind commuting a little bit for the right area. Thanks for any help you can give!
