Room in house with large garden and park close by.

I am a single parent teacher looking for a room mate, preferably female and who works with children or knows and understands children, to live in my spare room. It would need to be a tidy person who is positive and chatty as I would like to enjoy this arrangement.
Large house with gardens (0.2 if an acre) and plenty of off-road parking.
My children live with me every other week, they are 8 and 9. We have a cat, he doesn’t do an awful lot as he is 15. He abides by house rules and can’t get onto surfaces due to his arthritis (pic from his youth!) We have three living area rooms: dining room, sitting room and hobby room plus kitchen so lots of space to get away for alone time if needed. There is also a very secluded spot at the end of the garden which is about 30ft by 40ft and is very calming with hammocks. There gardens are well maintained as is the house but the person renting would be expected to keep the space clean and tidy from their own messes.
