Hi@Stephanie
Im Sorry I have misunderstood your post, apologies.
I never think of an air bnb in terms of a self catering environment as I always book with hosts who live in their family home or own apartment as I avidly avoid the host for whom air bnb is a burgeoning business with several apartments, units etc.
I strip the beds myself so I turn over and hoover the mattress to hoover up dust mites, and bugs etc.if any.
I live on site, I provide the use of my washing machine and electric tumble drier for a clearly stated fee for guests, to do a load of their personal clothing and intimate items.
They load their ‘smalls’ into the machine and take them out when finished.
I provide this paid use of my laundry facilities to prevent guests from washing clothes under the fully running hot shower=emptied previously full, hot and cold water tanks, with £200 plumbing bill too.
I provide paid use of the electric tumble drier,
to prevent guests from hanging dripping clothes from hangers in my wardrobe,
along my curtain rails,
along the top of the bed frame,
along my radiators,
along my shower cubicle
All causing an increase in humidity in my home environment with possible future mould spore growth, staining of newly decorated painted walls, etc.
Icing on the cake? The guests using my hairdrier for hours to dry some of their laundry.
All the above happened to me, hence my decision to provide paid use of my washing machine and tumble drier.
