I just did the exact trip you speak of, got back the 10th. We stayed at DMR (Durango Mountain Resort)... well across the street at the blackbear condos.
I would have preferred to be in Ouray or Silverton, closer to the action. This however wasn't bad, we could be in Silverton within about 30 minutes. Ouray took about an hour to get to.
It was nice that we were so centrally located that we could go down into Durango for an afternoon or evening. We could go North to Silverton, Ouray , or Telluride. We spent time in all of those towns, and ran many trails.
One suggestion, check out the old schoolhouse cafe that will be a few miles south of DMR. Phenomenal pizza and calzones!
Also, be careful driving back to DMR at night, I had way too many close calls with wildlife on the trips home at night!
Also, the book will be the best $ you can spend. I also used the Every Trail app, throughout the trip.
