@Michelle1851 If you are talking about that review from Sarah Jane, it isn't a negative review, aside from the mention of the musty odor. They gave many nice compliments on your hosting and how clean it was. It doesn't sound like they were unhappy at all. What they said about the distance to the village, the darkness in the parking lot, and maybe not a great place for noisy kids isn't negative, and don't come across as complaints- they are just comments for future guests to be aware of, and is actually a good warning for noisy people not to book, and to bring a flashlight. If you can't handle anything but purely glowing reviews, you need to toughen up.
You really shoudn't let strangers' illogical behavior affect you personally. There are a lot of people who are just unhappy and nothing is ever acceptable to them (but I don't read this review as such). They will find things to complain about no matter what. It has nothing to do with you and you aren't responsible for their outlook on life.
There could be a storm where the whole area's power goes out. One set of guests will take it in stride, and play board games by candlelight, tell ghost stories, decide that dinner will consist of eating up all the ice cream in the freezer before it melts, have a great time, and it will be a fun and unexpected part of their holiday. Another set of guests will tell you it "ruined" their vacation.
Let it go, it's their baggage, not yours.
