@Sume1 I see you're in a tricky situation. What's tricky about it is that you say you've become friends with this woman. Nothing wrong with feeling like friends especially in a long term stay, but....
This woman is treating you like an unpaid servant. A slave. There is no way that a paying guest should be expected to spend time deep cleaning this woman's house. It's outrageous, really. A good guest cleans up their own messes of course, takes care of their own laundry, bedding and towels ( if that was the arrangement you agreed to, which should have been mentioned in the house rules), maybe do some little extra thing if you're there long term if you feel like it, just to be nice. But honestly, she has a lot of nerve to ask you to do these things and if she actually mentioned it in the house rules, no one would book with her.
And she doesn't even have a change of bedding for you? She sounds like an incredible cheapskate.
If you hadn't said you were friends, I'd advise you to tell her in no uncertain terms that you paid for your stay, including a cleaning fee and that if she expects you to be her unpaid maid, you'll contact Airbnb to tell them this.
I'm not sure why you feel like friends with her,as she doesn't seem to be being particularly friendly to you- she won't let you hardly use the kitchen, even though you are there long-term, threatens that you'll have to pay if you break anything, even though you haven't broken anything, hasn't provided you with a change of bedding, yet wants you to wash the sheets for 15 minutes, max. and wants you to spend what sounds like hours a week cleaning her house for her. Sounds like she should be paying you.
But since you didn't kibosh this the moment she informed you of her non-mentioned in house rules requirements, I really can't think of how you could approach this without it turning into a bad scene. I hope some other hosts can advise you here.
