My DW and I sailed on the Carnival Liberty last June. By looking a the deck plans, the cabin numbers that you are referring to appear to be category 1A, interior stateroom that features upper and lower beds.
Go to Carnival's website and find a sailing date for the Liberty. From there you can find both a deck plan and a picture of the stateroom.
My wife and I both loved the Liberty. It was nicely decorated and didn't have that "over the top/glitzy" decor that Carnival if famous for and the food was excellent.
