I don't see how that could even be an issue. You can put their enclosure where ever you want, maybe avoid rooms that are particularly cold, hot, poorly ventilated, or very dusty. I don't see how a bedroom could be an issue unless they have any of these problems. Just like other possessions, lot of people keep caged pets in their bed rooms especially if there's more than 1 person living with them, cause it's their pet, their responsibility, their room.
