Does anyone mine with their Antminer in their bedrooms/room they spend most of their time in? Does it get too hot? Will you be able to have multiple Antminer's in your room in the summer?
Yes it will get warm in the room. I'm in a cold climate and I haven't used any (other) heat this winter.
Summer where? You probably want to keep the temperature below 90-95 F as most computer equipment is specified to operate at that ambient temperature or below. If you are running these in a hot climate you probably want to air condition down 85 or 90 F (or lower if you want the fans quiet).
Also, at least when they are new there are some "new electronics" odors/fumes. I wouldn't want that or the noise in my bedroom. "Low noise" fans won't work unless the room is cool. For the most part "low noise" fans just run slower.
