Looking for an apartment in Denver to rent for only one month?

I'm currently living in New Jersey, but am thinking of going to Denver for one month in October to take a TEFL class. I've never had to find my own apartment before so I'm not quite sure how to go about this. So far I've found a lot of places that seem to be more long term. Are there any good websites to look at. Also I'm looking for furnished as I don't want to have to bring a ton of stuff for one month.
