Sorry to hear about your experience @Rossana121 . @Anonymous and @Robin4 have given you some good advice. We learned too about setting expectations for guests in advance so there are no misunderstandings. This is especially important during the pandemic for everyone's safety! The cleaning fee isn't an issue since we don't provide the service during stays.
At our rental, we tack on the following statement to our guest message whenever there is a booking for 7 days or more:
"LONG-TERM RENTAL NOTICE: Since you are staying for 7 days or more, please be aware of the following conditions. All of the consumable amenities are for your use free-of-charge. We won’t replace them during your visit, but they are provided for your convenience. There are grocery and convenience stores located nearby and noted in the online Guidebook.
There is no cleaning done at any time throughout your stay. Guests are responsible for using the supplies provided (under the sink and in the dining room closet) to maintain the premises. Fresh sheets and towels may be requested on a weekly basis. We’ll normally check-in with you to see if you need anything every 7 days. However, don’t hesitate to contact us sooner if you have questions or need assistance.
Garbage & recycling pick-up is on Tuesdays. You are welcome to handle the disposal yourself at any time in the rear of the property."
Our last long term guest washed the sheets and towels herself since we have laundry facilities available for guests (she chose to do this; normally, we're willing to do the task).
Good luck with your listing!
