The black spots in the tub were from a bath mat being removed and no scrubbing being done. The unit also smelled horrible. When I mentioned this the host decided to begin debating if they were dirt spots or rust marks. That does not change the fact that the cleaning job that was done was inadequate, actually it smelled like no cleaning had been done at all the carpet in the living room is 3 shade’s darker in spots where it should be white. The marks in the bottom of the tub were lighted by scrubbing, the shower head is disgusting. Bottom line, the place needs a deep clean.
