DO yourself a favour and use another service. TRUST ME.
I was actually recommended this service from someone who has used them for years.
The first lady they sent me was great. She came for a few months, but then left the company. The replacement cleaners have been terrible. I asked for the first one to be changed since she didn't do a good job. The second one was even worse - and had obviously not cleaned a bunch of things (including the ENTIRE upstairs floor of my house). There was obviously stuff on the floor that she hadn't bothered vacuuming, dusting, etc.
I complained and even took pictures on my camera phone, but when they sent the same lady back a day and a half later to fix what she hadn't done, she basically stood in my house with her hands on her hips and accused me of shedding dust and hair on purpose since it 'wasn't there when she cleaned'. I have no interest in dirtying up my house to get it cleaned again, I assure you.
She's still here and banging my furniture around in protest like she wants to break it. Also, she finally admitted that she hadn't cleaned one of the bathtubs the last two (bi-weekly) visits.
ETA: I just went upstairs and there is STILL hair and fluff on the ground, despite her having 're-cleaned' it.
I bet she's going to try and blame the (very expensive) vacuum cleaner.
... update: She has now accused me of having too much hair. Amazing.
Rest assured, I will NEVER be using this service again.
