From the outset, let me state up front that we throughly enjoyed our time in Aspen. As for the property, it possesses some real plusses and minuses. On the plus side, it is perfectly situated in downtown Aspen; I don’t think you could pick a better spot from a location standpoint. Also, the property was well appointed in terms of stuff that you might unexpectedly need. We visited Aspen when it was unseasonably hot; the property does not have air conditioning (not uncommon in Colorado) but it did have a number of fans that saved us.
On the negative side: while the property itself is perfectly situated in core downtown Aspen, the building was a bit seedy. It is a multi-use building with commercial space below the residential space. There was a private elevator that was supposed to be secured nightly but that didn’t stop someone from relieving themself in the elevator. It was pretty disgusting. Also, the bedrooms in the back of the property are immediately below an alley with plenty of residential / commercial trash dumpsters (there is a restaurant at the bottom of the building). We were awakened quite early (5-6am daily) by garbage trucks, the smashing lids of the dumpsters, and other noises. And of course there was the smell that became an issue on occasion. Also be forewarned that the underground parking (also a plus) is quite small. If you are driving an SUV it will be quite precarious to park.
So overall, great location but with some warnings to be heeded.
