It might be a good idea to write down all your questions and run them by your counselor. You could talk to the manager of the sober house, too. Do you know the name of the place? If so, you could see if they have a website.
I think you're right that most sober living houses don't have medical detox - you might need to see a doctor about that. How long are you thinking about being there? If it were me, I'd really consider an extended stay.
So glad you're following through - there really is a light at the end of the tunnel!:ghug3
