Have been using this service for over 2 years now and it's our go-to especially for big jobs (our condo is over 2200 sf). They can send teams of any size which is great especially when we want to throw in once-in-a-while window-washing, deep spring cleaning or a thorough once-over of the outdoor grill. Now with a baby on the way, I'm particularly grateful that they can use their own less-harmful cleaning products!
They do charge marginally more than other cleaning services per person-hour, so for lighter, regular cleanings we sometimes go with someone else. But for a reliable, deep clean, Maret's can't be beat!
