I have a great housekeeper! Her name is Maria Boza and she works with her brother. They do cleaning for me twice a month and occiasonally her brother will fix stuff around my house. You can reach her at 240-351-3823. There is a slight language barrier, but everything has always been communicated to understanding.
For a service – I have used filipinohousecleaning.com (local, and family owned) – for my own house, and the rental unit when the tenants would move out. They are quick, they are thorough, they are prompt and pleasant – and my house smells AWESOME after they leave. I love it! I highly recommend. Good luck!
