Wow. That's a colossal mess, sorry you or anyone else has to deal with it. I hope the lady gets some help, she for sure needs it. And not just the drinking but the hoarding mess. When you get it all picked up and discarded, you might want to try a product called Urine Digester. It's for disinfecting and cleaning up the smell for anything that is organic based not just urine. I got mine at a janitorial supply store. It comes in many scents, lemon seems to work the best in my opinion. I've used this stuff several times and it really does work. It may take a couple of applications though. For a really bad mess I had to mix it up and use a pump sprayer, like you'd use in the garden.
