@Ellie354 Done. - But I think it's worth mentioning that Airbnb was set up to be an ACCOMMODATION platform. It would be against terms to use it for business purposes?
Another problem with your proposal/premise is than SOME guests don't go out during the day! - I know we Brits of a certain age (not you!) remember the days when B&B guests were expected to leave by 10.00am every morning and not come back till 5pm! But here in the CC there have been many discussions on this subject, and non-Brits have expressed horror that a space they "paid for" can not be utilised all day long, at any hour of the guest's choosing. It appears times have changed! And expectations!
So unless you are considering renting a self-contained space away from overnight guests, you might find your house a little crowded?!
