That sounds fine, I would just say ‘sotter can use the spare/guest room which opens to a common patio (with a locked door and shutters) or use our master which only opens to private space’.
Something like that. Again AI is super helpful with the exact words 
Yes that’s a far more useful description as the previous one sounded a bit off to me skim reading through your listing.
That sounds like that’s an easy fix. Just ask for regular daily updates and select someone who is comfortable with cats. I have so many cat pictures on my profile a homeowner recently asked me if I am travelling with my cat.
Thanks everyone for the helpful suggestions. I have updated my listing.
Well done- you took note of everyone’s ideas and feedback and this produced a much improved great listing. I see you’re now reviewing so it worked out really well. Best wishes.
