This seems like a reasonable beginning... There's a lot
left to do of course :) but I don't think you are headed
in the wrong direction...

It's common to begin ClassNames with Capitals. See
http://www.python.org/peps/pep-0008.html

Thus "class Room:" would be better.

You can write this as "if self.location.exists[0]:"
Being not equal to 0 is in this case the same as
being I assume. (The meaning will be different if
self.location.exits[0] could contain [] or "" etc, but
not if it only contains numbers. Zero is "false".

You could have something like
  directions = {'n':0, 'e':1, 's':2, 'w':3}
and then:
         if cmd in directions.keys():
             if self.location.exits[directions[cmd]]:
                 ...

Good luck!
