As others have said a Deep Clean is needed! it's fantastic value for such good connections to London and free parking, Bed oversized but very comfy, room large but musty, carpet past it's sell by date, bare floor boards and rugs would be my suggestion. I know how expensive it can be to update and keep older style properties clean as I'm running an Airbnb too. I feel it's worth it to hire a cleaner too when renting a lot! add to cleaning fee !
