"We appreciate the great job your staff does for the following reasons:

• They are always cheerful and friendly. In particular, they are nice to our dog, who does his best to slow them down and get in their way.

• They are honest and take responsibility for everything in our home while they're here.

• They do extra things. If our bed is already made,
  they touch it up and straighten the pillows, too, so that it looks as good as the rest of the house when
  they leave.

• Speaking of doing extra things, we really appreciate it that they move stuff around to clean a surface and don't just clean around it. They also clean things even if they don't look dirty.

• …We both travel, and we never have to worry that there will be someone we don't know coming into our home when we're gone. "
