Save the $$ and look into St. Christopher House. It is across the street from Exempla/St. Joseph Hospital....you can find a link to them through Exempla's site. You do not have to be a patient of Exempla to stay there! It costs around $35 a night/$500 per month for stays and it has all the amenities of a regular hotel.
PM with any questions! I am happy to help

PS-- how long are you staying in Denver for?
