Double Rm in architect-design house -lodger wanted

Available now, looking for a female lodger. Beautiful (small) double room on 1st floor overlooking garden, in our recently refurbished Victorian terraced house. My parents live downstairs in the house on the ground floor, with their own bedroom, bathroom, living/kitchen, office, it's their own flat.
And we (me 24, sister 22, brother 17) and you, will live in the upstairs floors, where we have our own bedrooms, bathrooms, kitchen/diner/living room, laundry and amenities. Our small dog moves across all floors in the house. We want a lodger for the upstairs floors & flat, plus it'll be a bit like living with a family too, yet you'll have lots of your own space.

You'll have 80% sole use of a bathroom (as we use the other bathroom).
