SIL newly disabled, housing

[user1473065575]

Hi, not sure where to post this so please direct me if there's a more appropriate board.
My SIL had cancer removed from her hip last October. The surgery got complicated and the end result has been a full leg/hip amputation.
She is finally ready to leave hospital. However her flat is completely unsuitable for a wheelchair. The council can't/won't help as they own the flat (a 1 bed, 2 adults, 2 kids, mortgaged, tiny bit of equity). We're really lost how to get her home, find suitable accommodation ourselves. Hence my post. Thanks so much for any advice you can give.

Is the flat unsuitable due to being on an upper floor?

They could rent it out and rent somewhere else themselves?

I repeated it on chat for traffic - will ask MN to close this one.

in summary it is ground floor but too narrow doorway/hallway to get a wheelchair through.
We are looking at renting it out and finding somewhere else but it definitely isn't easy to find somewhere that is wheelchair accessible - any advice? The search function on the property websites is pretty poor from what i can tell in my initial searches.
