Here's my cute little condo located just outside of downtown Aspen. Two nice bedrooms that can sleep four but might be a wee bit tight for longer visits. Right in between Snowmass and Buttermilk and on the bus line so you literally never have to drive anywhere. Walking distance to an amazing bakery, health food store and liquor store. The place has a pool and hot tub for apres ski (or apres hike) and it's just down right chill. WiFi and parking. No cable but a TV and DVD player for movie watching.
I'm a long time Aspen local so can give you tons of ideas on hikes, restaurants, bike rides, where to ski and ride and all that so hit me up if you need any insight.
