I think a 'place' (to generalise it) is quite a small object in any case. 
All it needs to contain is a few lists:
- a list of exits, which in some implementations might be simply
  references to other places, but might usefully be objects with
  two sides, each having an appearance and a link to the place 
  where that side appears.
- a list of fixed objects which only serve to describe the place.
- a list of mobile objects that actors can pick up and move
- a list of actors who happen to be there.

plus a describePlace() method and add(), remove() and getItem() methods 
for each list. It may be possible to use a single list for all types of 
object, in which case the object itself would be very small indeed.
