I'm having the same issue. Is there any way of getting certain scores changed?
I always request pointers from people who have marked me lower than I expect and some of the reasons are nothing to do with me or my efforts.
I have received a few lower cleanliness scores recently (I have a professional cleaner so was surprised). When I asked the last 2 why the low scores I was informed:
1) There was shampoo around the shampoo bottle in the shower - this was to be expected when they use bottles in the shower.
2) They brushed their hair in the room and as a result there was hair on the carpet. Again I'm not sure how I could have prevented this.
I'm not sure how I can resolve this as some people just seem to be harsh critics and forget this is a working home they are staying in.
