Not good.
They were unable to send the same crew each week so there was no continuity. Additionally, they were very very rough on our belongings. The broke a lazy susan in my kitchen and did not tell me. They also dragged expensive speakers (that they had been told multiple times not to touch) across our hardwood floors - and scratched them. They also moved everything around. When I have maids in, I expect the house to look reasonably the same except cleaner - not with everything moved around.
I was very clear to them from the beginning: I left notes every week and was told that my instructions were being put on file.
The owner called me about the scratched floors... said he would have them looked at / fixed. I cancelled service with them after they broke more things and have not heard back since.
