What a beautiful house! I'm ready to pack my bag!
I would definitely agree with maintaining your ability to approve all reservations without using instant book. Make sure you've checked comparable to price yourself right. Better photos, as you plan on (it's on my list as well!). Three sets of all bed and bath linens. And make sure your house rules include any disclaimers that will cover your butt in case of guests that lack common sense, aren't respectful of your home and it's decor, etc. Think about things that might lead to a guest wanting a refund or getting hurt, and disclaim disclaim! Make sure that's repeated in a printed guest manual on site. I now also require guests to acknowledge that they've read the listing, amenities, and house rules AGAIN 5 days prior to arrival. Good luck!
