Hi Andrea,
I think your sister is very brave and I know when my time comes I do not want to be in a hospital etc. I hope you find the perfect place for her, I already know I want to see the sunset or sunrise on our property before I go, and I am determined this will be my last memory this side.
I wish yourself and your sister well and I cant help you with a place, but I hope you truly find somewhere beautiful.
Blessed be.
Leesa
