I am a new host but set up my house assuming people will be curious. So far my few guests have been wonderful and respectful. Some use the common areas and some do not. On purpose, I charge more than what airbnb suggests because I do not want the guests who are looking for the cheapest deal out there. I rent out my master suite and offer living room, dining room and kitchen as common areas. I provide guests toiletries, snacks, tea and coffee, water, phone chargers, and all kinds of little amenities I like to have when I travel. I have a cat who needs access to my room and the common areas where her litter box and food are so do not lock my doors. I re-keyed all the locks inside my house so each bedroom will lock with an individual key but my bedroom key is the master key. So when the old cat is gone, I could lock my private areas. I have a closet I can lock with the same master key, drawers and cabinets on my antique dining room furnuture and desk that I lock when people are here. So I can lock up my liquor, antique silver and china, postage stamps, computer password book, and anything else I don't want people to access. I also have a locked outdoor shed and have considered hiding cash, passport and that type of stuff in the shed where no one would think to look. I always password lock my computer screen when I am done using it and my son has set up my wifi router with a guest log-in so even a hacker cannot access my personal wifi channel. That way if someone watches child porn or does something illegal, it can be traced to the guest. I love to entertain friends so always have extra food, drinks, dinnerware, etc on hand. Although I don't want my stuff damaged or abused, no piece of furniture or rug is worth more than a few thousand dollars. If guests peek in the linen closet, pantry, or even my clothes closet, they will not find anything interesting. I don't keep my great-grandmother's silver or china out where it can be accessed. I have no problem with guests helping themselves to ketchup, mustard, butter, olive oil, salt and pepper, an apple, a bottle of water or using the appliances. If they were out-of-town family members staying with me, they would be using my stuff the same way but I wouldn't be making money from their stay! Some people are certainly more considerate than others but I guess that is the purpose of the ratings and reviews.
