Airbnb 1st time rental wants $ back for slow water pressure

[Luann Renteria]

I we during the property next to us into an air BNB and rented it out for a month Two weeks after we posted the property.    Wasn't expecting and in the middle of Michigan in the Winter and it has been a learning experience.   The renters Have said a few times if you take care of us will take care of you. Which makes me very leery. On Friday they contacted air BNB and said there  was mold, construction happening, and low water pressure.   We immediately went over to investigate.   The only issue is low water pressure in the kitchen.   We have called a plumber and I let them know.  They now want compensation as its intruding on their months holiday. They got a great deal, about $35 a night (I'm learning) What should I do?
