@Mary-Ann0:
I agree with what others have mentioned with regards to suggesting you write shorter reviews in the future, if the issue was resolved, I wouldn't recommend mentioning it. It is tricky to have guests use the same towels/sheets etc for longer stays. Did you provide replacements in the unit?
My suggestions:
Shorter Review: ------ and her husband --- were quiet, helpful, and unobtrusive guests. Thanks so much Don and thanks for the nice remarks shortly after you arrived saying my place was “so clean and everything". Glad to know they enjoyed our unit as much as they did during their month long stay.
They helped you with something and in return there was a grease mark on one of the sheets. It happens.
-For month long stays, offer a weekly light housekeeping service: freshen sheets/towels, clean the bathroom (especially), and touch up in the kitchen type deal. Or consider offering a full on cleaning service every 2 weeks. Whether you build it into your nightly rate or state that guests are responsible for a 2nd cleaning fee for month long stays in your rules. This helps protect your home and the things in it.
-While we hope everyone knows the golden rule to wash the dishes one uses, that cannot be assumed. If this is an expectation you have, I would add it to your house rules.
-If for some reason the guest refuses the weekly or bi-monthly housekeeping service, you can either make it a non-negotiable item OR expect for your home to need a deeper cleaning than usual.
I don't want to judge you on your $100 cleaning fee (we charge $50 for a studio and pay our housekeeper $60, we recognize others in our area charge farless but I am not willing to compromise quality, dependability, and trusthworthiness that the job will get done right each and every single time.) During a few longer stays we have had, we have offered housekeeping on a weekly or every 10 days or so.
With the disclaimer that I am not trying to judge you on your cleaning fee, I did check similar listings in your area, the first that popped up under entire home was a 4 bedroom house which accommodates 8 people, they charge a $150 cleaning fee. Maybe the guests felt justified they paid a "premium cleaning fee" and felt them taking out the trash, clearing the fridge, rinsing the dishes etc was enough after a month long use.
Even if our listing offered a full on kitchen (we don't) our housekeeper would still be replacing and or washing all the dishes/utensils etc provided in our unit.
Just some thoughts:)
