Single room in welcoming home

I am a live-in landlady. This is a 5 bedroom house but 2 rooms are kept empty as they are my children’s rooms. They are grown up and have homes of their own.
One other room apart from mine is occupied. You will have a separate kitchen and bathroom from me but shared with the other lodger. You will also have access to a shared living room separate from my main living room.
The room is a single room with storage under the bed, a double wardrobe, a desk and chair.
I have the friendliest lovely dog - a cockapoo called Ruby.
I’d prefer to have a graduate professional living in the house. I am a maths adviser and tutor. I like chatting about travel and work. I am friendly and approachable but you’d have as much privacy as you need. We are 10 mins by bus away from Goodmayes (Elizabeth line) and Barking ( District, Hammersmith& City line and Overground)
