Cleanby4star is owned by Jennifer Zalewski, who does all of the cleaning herself, so you do not a different set of people in your home every time. She does a thorough job and happily takes requests for special things you might want done. She is very picky about her cleaning, and does the wood floors on her knees because she worries about missing something if she uses a mop. She has a wonderful referral program and is very flexible about scheduling appointments. I am very glad we found her and can avoid impersonal large companies. She works all over northern Virginia.
