Need help with a query. Probably a self join or a nested query.

I am having difficulty with a query. I have tried a nested query and
self join, but just can't get it. So possibly someone can help me out?

I have a table below and obviously it has redundant data. basically all of
the codes are associated with a description. I don't care which description
is returned from my query. I only want a unique code, and the description
associated with the unique code. Can someone help me out? Below is my table
Apartements and below that is the resulting query of data I would like returned.

Table Name "Apartements"

Code     Description
TB       Two Bedroom 1 bath
TB       Two Bedroom
TB       Two Bedroom plus patio
OB       One Bedroom
OB       One Bedroom plus sink
OB       One Bedroom plus 1 bath
FB       Four Bedroom
FB       Four Bedroom plus 2 bathrooms
RU       One night rental unit
RU       One Night with breakfast



Resulting Query :

TB      TWo Bedroom 1 bath
OB      One Bedroom
FB      Four Bedroom
RU      One night with breakfast
