Hello @Bonnie81
I have a different target guest group than most ABB hosts - I host mostly long term (exchange student) guests in my private room/shared home listing. My guests stay anywhere from 1 to 4 months so I think I can offer a slightly different approach.
In my case, I provide bed sheet changes every 2~3 weeks (usually 2) but I tell guests they can ask for new sheets before the usual 2 week change if they need/want a sheet change for whatever reason. I keep a supply of towels (3 hand +2 bath) and extra rolls of TP in the guest bath cabinet and replenish once a week. Henry vaccums the common areas once or twice a week so he usually "airs" the room, shakes out the blanket, and does a quick vaccum of the guest bedroom floor and under the bed (without disturbing the guest's personal items). This is also when we check if the guest needs more kleenex in the room and empty the trash bins. We prefer to handle the laundry for towels and bed sheets, so guests are responsible for their personal laundry only (we allow 1 load per week to guests staying longer than 1 week). We keep an eye on the guest bathroom and scrub the corners maybe once a month to keep it hygienic, but guests are ultimately responsible for keeping the guest bedroom and bathroom tidy. There are also wet wipes, rags and a dust buster located in a corner of the common area that guests can use for basic clean up and most of our guests have been very respectful of our home 🙂
I've had a few people tell me that a 2 week cycle for bed sheet changes is way too long..... but it's the frequency I change my own sheets. I tend to shower in the evening before bed, and I do not sweat easily so I understand some people may need more frequent changes but considering most of my guests would have looked at shared room dormitories before deciding to book with me I couldn't help but think "how many college age kids living in a 2~3 person dorm room wash and change their sheets every week????" So IMHO, new sheets every 2 weeks seemed sufficient and I haven't had any complaints yet. And during the summer, I end up changing the sheets at day 12~13ish.
Hope this helps~!
