How about Room 10? It's a four-bed dorm; Steve would be in with Bisi, who is a player character (teenager who uses a wheelchair) and two kedan.

Also, would you like to thread out his check-in? I wasn't sure Anton would talk to Steve directly on his network post unless prompted, because he thinks it's rude to spill his fan everywhere, and I wasn't sure what you had planned with Steve's living situation at that point.
