@Christina583 I do make an effort to make sure common spaces are much cleaner when I have a guest than when I don't. It is a bit exhausting, but I feel it's necessary. I don't think everything has to be absolutely spotless in the spaces you also use, but I make sure I do clean the guest room and their private bathroom impeccably. I'd never use a stained sheet or towel for guests, but as I'm a seamstress, I might patch a little hole with some cool fabric and my guests have even commented on how cool it looked. And an unwrapped toothbrush in the cabinet, even if it's new and pristine- you know it is, but the guests don't.
I'm not one of those hosts who irons the sheets, nor do I wash the mattress pad and blankets every time between guests, but I only host 1 person at a time, and all my guests so far have been clean people who shower before bed, so it's not like anyone's been having sex games on the sheets or on top of the bed cover.
It's hard when you've got kids and a busy life to stay on top of everything, but at least making sure the guest room and bathroom is super clean, nothing stained, no toiletries that look like they may have been used, no shampoo dripped down the outside of the bottle, no dust bunnies under the bed, no grubby fingerprints on the light switches, etc. is important, IMO.
