@Craig-And-Christina0 First off, your place looks really nice and your listing info is well written- you've put a personal touch into the text, as opposed to some listing descriptions which read like a generic rental ad. Putting the personal touch in helps to get guests who are respectful, so you've got that base covered. Also you have wonderful reviews- people obviously love your place and appreciate what you provide.
A few suggestions- it looks like you use Instant Book? While this definitely puts you up in the search rankings, it limits your ability to vet guests before they are allowed to book. Hosts need to weigh the advantages vs. the disadvantages of using IB. If guests need to send an Inquiry or Booking Request before a booking is confirmed, this gives you the opportunity to get a feel for whether a guest is a good fit for you.
It seems to be a fact, according to posts on this forum, that entire house listings can be problematic as far as guests respecting the space and leaving it clean, as opposed to places with an on-site host. You state in your listing that "the place is all yours" (that may not be an exact quote)- I don't know how close you live to the listing, but if it's not far (some hosts live hours away from their rental), you might want to amend that wording to something like "This is an entire home listing, however we live quite close and are readily available should you have any questions or need assistance with anything". This lets the guests know that you might drop by at any time (with prior communication of course) so they are more likely to keep the place in good order. Some hosts with whole house listings say they make it a point to let the guests know that they'll be coming by to introduce themselves and check that the guests have found all they need shortly after check-in.
You might also state somewhere in your listing info that this was your primary residence for many years and has sentimental value to you and that you expect guests to respect the place as if it were their own home.
In your communication via messaging when a guest books, if you don't already, you might make it clear what you expect guests to do re cleaning- i.e. leave the kitchen clean (dishes washed, stovetop clean- explain that the cleaning fee is intended to cover heavy-duty cleaning, laundry, putting out fresh supplies, etc, not cleaning up personal messes). Also put this loud and clear in a house manual on -site.
As far as guests taking the whole bag of supplies, some guest will do this, as they think it is all there for them. This is also something to make clear in a house manual. "Feel free to use the supplies provided during your stay, but we would appreciate you leaving the bag they are supplied in". Or don't leave out anything you don't want a guest to possibly make off with.
A comment re your photos, altho this has nothing to do with the type of guests you attract- the 2 opening photos of the front of the house are redundant- I find the second one a nicer shot and would use that as the cover photo and ditch the first one. You have no photo of the bathroom facilities- put in one of those, guest like to see the bathroom (no straight-on shots of the toilet and toilet lid closed- I can't believe how many hosts take open-lid toilet photos). I'd also eliminate the backyard photo which looks out on the house behind- the yard doesn't look that attractive in that shot and your other photo of the back of the house makes it clear that there is a yard there.
Hope this helps somewhat and that you get the kind of guests who respect the place going forward- you're obviously great hosts according to your reviews.
