NBR: Recommend your cleaning service/lady

We live in Medford (near bus and commuter rail) and are looking for a cleaning lady/cleaning service for our 2 BR apartment.  Ideally, someone with reasonable rates who is thorough and trustworthy since we'll be at work.  

Anyone have someone they'd like to recommend?  What do you like about them?

 We had 2 wonderful women come every 2 weeks when we lived in New Haven...it's been 2 years and I miss them! 

Thanks in advance!
