We have used Naturally Clean twice now (just signed up for regular service!) and they really do an amazing job. They're super easy to work with and accommodating scheduling-wise and they really get our condo clean in all the obvious ways but also in the nooks and crannies (the place I'm terrible with!)
I definitely recommend their services and love that they are able to communicate via email and text messaging. Plus, I'm a huge advocate for not exposing ourselves to unnecessary chemicals and am happy to have found awesome cleaners who use safe products!
