So sorry this has happened to you, you have a great get away place!
As it is, review time is over, time to move on.
But if I may, a few suggestions, hopefully helpful:
1.) I see your new house rules about no kids. No problem, but I would take out the part that someone else broke stuff, etc.. Don't punish new guests for the sins of the previous ones, just drop it, that will sound a whole lot better.
2.) If I were to consider renting your place I would want to see more pictures of the place, not so much of the lake, skiing, etc. I would want to see the other bedroom (s), the kitchen, the bathrooms, etc. and more of a description of the place itself.
As you now won't accept children any longer (we don't either, I relate), I would take out the picture of the princess room (lock it up when guests come) and the playground. Perhaps limit the number of guests to max 4-6?? ( 2 in the queen bedroom, max 4 in the double bed/bunkbed room, none in the common area , that just invites camp out wild behavior. The more people you have, the more trouble that brings....
3.) Give yourself a break and be more specific with check in and check out times, narrow them down, prevents trouble down the road. Nobody offers or expects a place to be ready at 10 am for that day's rental, as you have it right now.
4.) about reviewing guests: we hosts want to rely on what other hosts have said about someone, right? But we hardly can, as quite often, even if hosts have gripes, they leave stellar reviews on those guests. I see that your guest Bill was the one complaining about the heat. Is that the one with the lamp and the mess? You answered him on your site , also saying that you were unhappy about his smoking, yet in your review on his profile you praise him and highly recommend him... just an example how we as hosts need to stick together and let honesty prevail.
And now, good luck for the future, and happy hosting!
