@Stella465 At quick glance a few things pop out. It’s a beautiful space obviously, but you represent it more as a gallery of unique furnishings and decor, than an accommodation. It’s listed as a private room in rental unit, with shared kitchen but nowhere do you explain who guests are sharing the space with.
Also “You can use the living room as a creative and shoot/studio space when my clients aren't using it.” Um, what? You mean perfect strangers may be randomly accessing the space while guests are installed? That’s potentially problematic, and needs very explicit explanation, and do be sure guests are aware of what the arrangement is before they book.
Re your check in window and check out time, are you blocking days between bookings?
