I used Merry Maids from April 2007 until August 2007. The very first cleaning the maids ripped a number of blinds, left them on the floor and broke the pull mechanism. They also broke my kitchen oven handle. The maids are not careful and try to finish as fast as possible, resulting in broken items. The items were repaired but took two months to complete.
Cons: Expensive, broken items, bad cleaning
