You can try something along these lines:
Code:
Studio Apartment is a room. The cooker is a device in Studio Apartment. The shower is an enterable container in Studio Apartment. The hoojab is in Studio Apartment.
Using is an action applying to one thing. Understand "use [something]" as using.
Instead of using: say "You'll have to be more specific about how you want to use [the noun]."
Instead of using the cooker: try switching on the cooker.
Instead of using the shower: try entering the shower.
And so on for other things that you can use. You'll probably want to implement switching on the devices so that they'll do something.
What was the code you were trying that didn't work? (One trap I fell into: you can't write "switching the cooker on," it has to be "switching on the cooker.")
