Well, there are many templates/examples on the Internet that you can download and modify according to your specificity. Here is an example of my Houseguest Etiquette, which has been revised repeately according to new issues that emerge associated with individual habits and cultural differences.
1. Say "Hi" and exchange such pleasantries as "How are you?" and "How was your day?" whenever you run into someone in the house, be it your host or your fellow resident or a visitor. Some guests in the past from different cultures simply look away when they run into someone in the house, which is considered a little weird and even rude in North America.
2. Ask about house rules. Most guests would ask about certain house rules, such as curfew. This shows their respect for and consideration of other residents, which is very nice.
3. If you are not sure about anything, ask first. If you have done something you are not sure about, explain afterwards. Each house is different, and may have certain functions/features you are not familiar with. Do not attempt to guess if you are not sure about anything. Simply ask me. And I will be always happy to answer.
4. Conserve towels and linens. I do provide several towels and prepare extra linens. Most guests would just use one during their stay. Some guests bring their own bath towel and linen, which is also what I would do whey I stay at a hotel.
5. Bring your own toiletries. Most guests use their own toiletries. However, a couple of guests I had before used another resident's toiletries without asking, so that we had to put a label on his personal effects. I do provide basic toiletries, but using other people's personal toiletries without their consent is not encouraged.
6. Respect common areas. I have not observed big problems in this regard. Most of my guests respect common areas. However, some male guests stand up to urinate and may leave urine stains on the toilet and the floor, which is not respectful to the next user. So I have put a sit-to-urinate label on the toilet tank. I do clean the guest bathroom on a daily basis, but I'm unable to clean it right after each person's use. So, guests are encouraged to maintain the cleanliness right after their use.
7. If you enjoyed your stay, leave a thank-you note or a great review. My family and friends all joke that I'm doing Airbnb almost like charity because my prices are among the lowest in Metro Vancouver, and what I earn can barely cover all bills. The reason my prices are good is because I'm a newbie in the business and I'm accumulating positive reviews. I try to be a great host and I hope my guests know it and appreciate what I offer.
