I truly don't see a problem with this if your eventually going to give free reign over the house to him. My previous GSD had free range of my house, and slept next to my parents bed. He would breath next to them only loud enough to let them know if he had to go out during the night. As long as his privelages are earned, and not given for free. Also make sure if you do sleep in same room, you do always sleep on a higher surface then him. Just to enforce leadership roles. There is no one right way to do anything. Each dog does vary, and you should focus on what works with yours the best.
