Guests can be high maintenance. If there’s an ‘on’ switch you can pretty much guarantee it will be found and be switched on whatever it is, and in spite of weather conditions. AirCon, heating, windows and doors open, wood burner lit... Yep, had that!
Before you blame guests for their complaining and consumption - which they do think is their right and legal entitlement- there are things you might consider doing:
When in use, your Heating shouldn’t over run the fuse board. That’s just an indication that there’s something wrong. Guests will be annoyed and you will be annoyed.
Your Yard & Garden is listed as an amenity but your description makes it off limits. Guests don’t read - so there is potential conflict there.
Your place is listed as an entire home - but you share the kitchen. I’m sure that might be an issue with some guests not fully understanding how your place works.
Many guests will look at photos rather than read your listing details. On your photos, make sure that you use the title space to state for instance “Backyard - No guest access”. I’m not sure whether you do this already as I never ventured onto your photos, but most hosts miss that and the guests expectations are that whatever is in the photos is theirs to use. Having the descriptions there makes your message clear.
I hope that helps.
P.S. Heading over for a legend breakfast.
