Free room in exchange for household duties.

My brother in law has just lost his wife. We are looking for a live in help. He is 82 and has all his marbles. In exchange for a token rent, we will expect the lodger to do cleaning, washing, and cook an evening meal. Beautiful bungalow in its own grounds. Large converted loft would be your spacious bedroom. Would suit someone who works from home or has a part time job, or even a student. Close to bus stops.
I would stress he is totally independent and drives, but he needs company more than anything.
We would need personal references obviously, but open to any sex/ age as personality is everything.
The “ work “ involved is only minimal about an hour a day at most.
He has a great sense of humour and is great for his age,
