I had Sunshine do my carpets (using a Groupon) a few months ago. The owner was on time but arrived in a huff, and told me he had just fired his employee that morning. So he brought his girlfriend to assist.
He charged me an additional $60 for heavily soiled areas. His square footage calculation for what was "soiled" was quite liberal but whatever, its a Groupon.
The carpets were clean, I guess, nothing spectacular. First four reviews look pretty fake though --- written in promotional language, in a few week period, and all by people who never wrote another review. Oh, and they're all five stars. Take that into consideration.
