Hi Kathy,
You will find that the Old Key West Villas are very well equipped. All the bed and bath basics (sheets, towels, soap, tissues, shampoo, etc,) will be there, plus you will have lots of equipment available in your kitchen. Making breakfast in your room will be a breeze. The post here lists all the
supplies in the DVC Villas at the Wilderness Lodge. The supplies at Old Key West are virtually identical.
If you are staying at OKW paying cash, you will have daily housekeeping service. If you are staying using Disney Vacation Club points, then you will have "trash and towel service" on day four of your stay, and a full service on day eight of your stay.
There is a regular "Mr. Coffee" type pot in your room. The villas have the standard 12 cup size pot.
You may want to head over to the independent website DisneyFoodBlog.com and search there for a series of articles called "DVC Villa Kitchens." This will give you a pretty good idea of what to expect in your room.
Good luck with your planning. Please let us know if you have additional questions.
