I stayed at Jason's place in August 2017. I was barely at the house and cleaned it top-to-bottom before I left.
When I got home I received a $150 charge for allegedly allowing the hot tub to become "grimy." When I asked for an explanation, the host gave me a very dissatisfying answer, essentially to the tune of -- "I have determined that the hot tub was grimy, and the house rules say that if you allow the hot tub to become grimy, then you owe me $150." I obviously I do not live in Dallas and cannot adequately refute whether the hot tub was "grimy."
He also charged me $10 for failure to empty a trash can and $20 for another bogus charge that I have no clue if its valid or not (bending a window "slat" (?)).
This guy is clearly out to extort people for additional money. He will charge you money at his sole discretion knowing you have no recourse.
