@Innocenza-Lucy0 I've never been a fan of white sheets for Airbnbs. People who are accustomed to hotels (or hospitals) often think of them as seeming cleaner, but that's largely because hotels use heavy-duty industrial laundries.
If you're using a consumer-grade washing machine, non-white linens (linens of color?) may suit your rotation better while also opening up more design possibilities. The brand and quality of the sheets doesn't make a difference when it comes to stains, but where you do really see the difference is in longevity - how many washes those sheets can take before the fabric starts to wear down and tear more easily. Removing bleach from the equation helps too.
