Remove any soft furnishings that can have a suitcase set down on it and have bedbug transfer, like the furry rugs I saw in one of your properties.
Purchase bed bug encasements for your mattresses (and box springs). This should make you feel better about protecting your furnishings from a possible infestation. Read up on how to disinfect your bedding between guests and how to treat your washer and dryer after the laundry.
If you want your guests to feel super confident that the beds are bedbug free, bundle/package the sheets and bedding and let the guest know that this is done for their own protection, and you are providing a pristine accommodation.
Best wishes!
