The room you didn’t book has its own private bathroom which you may not know. Apart from the bathroom upstairs, we also have another toilet with sink downstairs.
The size of my house and all rooms are bigger than others compare to the most other houses in England. For example, the single room you have stayed in has a single bed, two bedsides, a sofa, a desk and a chair, a shoe cabinet, a small wardrobe and a small chest of drawers. Apart from all these furnitures in the single room, there is built in shelf available, also space in the middle of the room. If you could have had the chance to stay in the single room in other houses, you would definitely find out that my single room is a spacious single room.
From all above, I have to say your description of my house and my room is not accurate I am afraid.
