Best ways to find senior citizen friendly rentals.

Hi everyone ☺️

My elderly mother is looking for an apartment.

I'm trying online with Lexpress etc.

Are there any better websites or local Facebook groups you would recommend?

I've been told there are also sometimes house shares with a group of senior ladies living together, but I have no idea how I would try to find something like that ☺️

Any advice would be hugely appreciated, thank you ❤️
