At the very least, you should look for specialty products that neutralize pet odor and put it on the floor, or else the cat(s) will continue to urinate on that section of the floor. I believe they're enzyme based, and you should be able to find them in pet supply stores and online. Just because you, a human, can't smell urine doesn't mean the scent is gone. Cats (and dogs) can and do seek out spots where prior urination has occurred and then add their own.
That said, I talked to my husband who has managed vintage (wooden floor) apartment buildings, and he said it sounds like the floor is pretty ruined. Urine, but cat urine especially, is very caustic. Cat spray can literally eat through walls and doors and floors if given enough time and applications.
