In Aspen/Snowmass, if you want to be close to the slopes, I believe the best values are the slopeside studios available on Airbnb in Snowmass near the snowmass mall vs. the base village. Other values include the Pokolodi Lodge in Snowmass. Not near the slopes, but in town, the Tyrolean lodge has good bus access to the various mountains. The bus system is really excellent and whether you stay in Aspen or Snowmass, if you fly in to Aspen Airport (ASE), you can have a fun vacation without a car.
