Maid for You is great. We have them come in every other week - they have a key and are in and out before we even know it. Beds are made like we're living in a hotel! Bathrooms clean, floors good. My sense is they aren't working on the clock - they are just there to get the place clean.
Piece of advice: Tell them ahead of time or leave a note if you want something in particular worked on.
Pros: Trustworthy, diligent, detail-focused
