Single room at family home for a female Christian

We are a Christian family with three children 7 to 17yrs in Cheadle Hulme. We have one 28 year old Christian female lodger downstairs and we have a single room upstairs for another Christian female young adult. Both parents work for The Message Trust which is a Christian charity. One of our lodgers is moving out in either June or July hence the August start date. It is a small single room with a vanity area and sink, a built in wardrobe, slim tall chest of drawers and a memory foam bed with drawers underneath. We have a living room for lodgers to use with sky tv and the kitchen is open planned to the main living room. £300 covers the room and bills. You would need to buy and cook your own food (cupboard space and use of the lodgers fridge freezer is given):
