Best living choice for care?

I’m in my mid 70’s and need a walker full time, with some health issues. My husband is 90 and unable to use his walker without someone assisting him and walking with him to prevent falling. He is very unstable... he is unable to get to and from the bathroom on his own. He needs assistance for all of his needs, in and out of bed, cannot stand on his own, dressing himself, cleaning himself, medications, doctors appointments. He can still feed himself he spends most of his day in his recliner with help going in and out of the bathroom... nights he uses a urinal. He has been diagnosed with Alzheimer's and yes, I know they are under the same umbrella. His mentality is in the early stages but his cognitive, physical issues are more advanced. Our son currently lives with us and does 95% of his care. I do what I can but limited in my physical abilities. I need a care facility that we can stay in together. Any suggestions or info would be greatly appreciated.
