I found Maryanna on Homestars and hired her based on her excelent reviews. I have been trying to find someone that cleans well and to my expectations for a very long time, and I am very happy to say I finally did. Maryanna did a great job with our big house. Before her we always tried companies that charge by the hour, which didn't work for us, since they tend to spend the whole day in your house just to be able to charge you more. Maryanna came a day before the clean up to give us a quote based on the size of the house and the amount of hardwood and tile floors. Then next day came to work from 2-5pm non-stop. I was very impressed with how quick and how well she cleaned. So of course we decided to hire her on a regular basis, for a clean up every two weeks. 100% recommended!
