I never understand why people worry about this enough to post asking about it. If you're a real couple, why WOULD you be worried about it? Immi isn't there to inspect the cleanliness of your house or how healthy the food in your fridge is - they're there to see if you're really living together as a couple, and if you're legit, you'd have nothing to worry about if they dropped by. My husband and I would welcome the chance to show them around, show them where we sleep, etc. as it would just be more great evidence to show them we're a real, married, very-much-in-love married couple. I always wonder (perhaps unfairly!) if people who post this question are worried because they're hiding something.
