I did the same thing where I lived with and provided support for a woman with cerebral palsy. As far as where they move or the type of property, you can voice your opinion, but this is your roommate's residence, so they will choose a place that is good for her (close to her job if she has one, close to family and the facility that manages her support). Now, if they do choose a place that is not good for her situation, you can tell her case manager, but other than that, it is her choice.
As far as where things are organized in the kitchen and decorations, you can decide these with your roommate as you would with any other roommate, but you have to have an extra sense of sensitivity. As with my roommate, people who have autism have a much harder time dealing with change than other people and so you will have to pick your battles. It's a hard job to do, because you are giving up certain freedoms you would have in other places, but you are helping your roommate have a sense of independence. It's worth the sacrifices.
Make your room your sanctuary - you have every right to do what you want in there, as far as the other stuff, pick your battles as you are there to support her. Good luck!
