There is a tradeoff between the time, money, and energy you spend as a host doing your own laundering versus the amount of time or money you’d save by having it done professionally. If you already have a high-volume commercial washing machine or something very close to it, you might be okay with handling the laundry yourself. If you’re having to turn over your rental quickly, though, it might be worth it to invest in a laundry service and multiple sets of linens.
