<font color=e87400>Sodium BiCarbonate,,, AKA Baking Soda should do the trick, I'd get a couple pounds of it & mix it in 3 gallons of water then spray the entire area with it,, I mean spray anything that you can get wet, Floor, Walls, Ceiling <i>(the odors may be locked into those areas as well)</i>. If you can wet it, spray it <i>(Use however much it takes, & spray it LIBERALLY.)</i> Do this before you clean, then also after you clean, however afterwards you may want to use a lighter mixture or just use it sparingly so as not to leave much baking soda residue <i>(Shouldn't be much in any event). </i>
Baking Soda is one the the best Odor removers there is & is a primary ingredient in most powder products that kill pet odors.

PS When I said spray it before you clean, I mean like a DAY before you do,, Will make it more bearable for ya.
And If your going to use a Surface Cleaner to Clean the floor, for a soap I would use Borax, & An Oxi based detergent, together they should be fine at Killing the stains & further the odor elimination. Being that is an enclosed area I probably would not use Hot water seeing as the steam would fog the area up, chemicals will do the job thoroughly enough.
