My other tip would be to read the BNB information for hosts. Far too many start without fully understanding how BNB works and get themselves in troub.e
Having done this for a year - hear are my thoughts.
Have a clear window for check in say 3 - 9 p.m. or whatever works for you. When guests book confirm a time within this frame.
Don’t use instant book until you have hosted for a while - you will have little control over who books (Personally I wouldn’t ever use as I want to ensure a good fit - but for self catering I can understand this is less important)
Always check out how a guest has been reviewed and how they review other hosts before accepting a booking.
Make sure your house rules are up to scratch covering extra guests, noise, whether you accept children, check in and out times, whether guests can invite friends in, expectations around how the property should be left after use.
Decide on your cancellation policy - I have strict to help ensure I don’t get lots of last minute cancellations. Understand clearly how the cancellation policy works - hosts can easily get penalised for cancellation guests and it looks bad to potential guests if you show as cancellation your guests arrangements.
Set up your listing so that only fully verified guest can book.
Have a comprehensive guest book in your home covering how things work in the house, taxi’s, public transport, local attractions, restaurants etc
You will get lots of guests who don’t read your listings and ask questions you have already covered - breathe
