Zen Cleaning is a remarkable enterprise. I hired their service for a friend recovering from hip surgery, coming home in a week. The two gals from Zen Cleaning worked miracles and love what they do. When I returned to the apartment as they were finishing, they were both down on their hands and knees in the kitchen dealing with long neglected corners and baseboards. How good is that? My friend is very sensitive to scents and after Zen it smelled clean but not chemically. Perfect. 5 Stars for Zen Cleaning and their dedicated staff!
