We have a VRBO so we know how things are not always perfect.
One shower sprays in a cone and not direct on you, but it's ok, we just used the other shower.
One toilet handle broke off. That's ok, there are 2 other toilets.
The pool was full of leaves and there are test strips littered all over, we just skimmed the pool and cleaned up the garbage.
The edge of the pool is loose and if you step on it and don't know you can biff hard, ok, don't step there.
The mattresses are worn out and super soft, thats ok we just made a bed on the floor out of spare blankets and didn't fuss.
A lot of light bulbs are burned out, we just moved them around so we could see.
The iron had melted plastic/polyester on it and ruined my favorite shirt, that's ok, I understand the guest who did that just didn't say anything and so the host didn't know to get a new iron.
The check out instructions had us taking the garbage and recycling out to the curb, wash all dishes, and replace the key. Ok that's fine, seemed extensive but we also did a load of towels and gathered all linens to one area because they seem like they have a hard time cleaning so we did our best to help them before their next guest.
After checking out, the owner accused us of having other people there even though we explained to her why blankets and the other bathrooms were used. Apparently the cleaning fee doesn't cover the whole house. If you are just a couple and not a large group and you're not allowed to use the whole place.
