i thought it was 3 weeks or a month...
you might be able to pull it off, but who knows, aspen is preeeeeetty much the most expensive place in co to find housing, especially once the season is underway and demand starts outstripping supply
as a general rule, extended stay housing for the season in CO (anything more than like a week) jumps 25-40% in price starting around late september and early october...
also, while it's common to find super short-term stuff like what youre looking for during, say, august (because people are leaving for a month or so before the season starts and want to fill their rooms for a couple weeks to avoid rent) it's more rare to find a situation like this when the season is underway. you might get lucky though and find someone whose roommate got fired and had to move out mid-month or something
but dont hold your breath
"Just ahead, over the rolling wheatfields all golden beneath the distant snows of Estes, I'd be seeing old Denver at last. I pictured myself in a Denver bar that night, with all the gang, and in their eyes I would be strange and ragged like the Prophet who has walked across the land to bring the dark Word, and the only Word I had was 'Wow!'"
