@Deanne52 One thing to be aware of, if you aren't already, is that any guest who asks for a discount, above and beyond any you might offer, is a giant red flag. You should decline those requests.
And the only reason to offer weekly or monthly discounts is if you really want or need to attract those bookings. In my case, and perhaps in yours also, given the location, my guests are coming on vacation- it's a destination beach town.
They aren't just passing through for a night or two, they aren't coming for work, or because they need a place to live, or all the other reasons people book Airbnbs.
So my average length booking, unless it's from a Mexican national, who might just book for a few nights because they aren't travelling that far, is a week to 2 weeks. There is no need for me to offer a weekly discount, because most guests are coming for that long anyway- it wouldn't bring me more business, because those guests only have a specific amount of time to be away on holiday. They have jobs and commitments to get back to.
BTW, your listing is lovely.
