My buns are in the living room. But oddly, they don't smell. They use their litter boxes, which I change every other day. And they are on linoleum, so there is no bedding. Don't worry- they still have boxes and soft stuff to cuddle.
For smells, you can try sprinkling carpets with baking soda on carpets and let it sit for about 15-20 minutes before you vaccuum- it will absorb the odors. Also, instead of spray airfreshners, or plug-ins, which just mask the odors- you can use Fridge packs of baking soda. Just open the vents and sit them out. Change monthly. If you can't find the fridge packs, you can pour the baking soda into a bowl. Also, vanilla absorbs odors, and smells good. You can put about a tablespoon in a small bowl and set it out.
There are more natural alternatives to chemicals, which are safer for your buns and for you.
