The room is thought to have some degree of sentience, because it transforms itself into whatever the witch or wizard needs it to be at that moment in time, although there are some limitations. For example, it cannot create food, as that is one of the five Principal Exceptions to Gamp's Law of Elemental Transfiguration. It is believed that the room is Unplottable, as it does not appear on the Marauder's Map, nor do its occupants, although this could simply be because James Potter, Remus Lupin, Sirius Black, and Peter Pettigrew never found the room.
