Found them on Craigslist and thought I'd give them a shot. They list prices and services which were reasonable. I went with the $98 for 2 ppl for 3 hours. They have an online booking service so I don't have to call or get a quote first which I prefer. I specified in my booking that I needed walls scrubbed. They sent out a reminder the day before to confirm.
I was texted the night before requesting my 8 am appointment be moved to 7 am since they had another appt at 10 and the 3 hours I booked would overlap that so my appointment got push to earlier. They then showed up 20 minutes late. I reminded them about the walls and let them to their work. Neither of the two people spoke english well enough to understand me beyond a few simple things.
They cleaned fairly well but didn't touch the walls at all which I had specifically requested and left promptly at 10 shorting us 20 min of work (if walls were done, it wouldn't have mattered) and headed to their next appointment at 10 which I assumed they showed up late for as well. They didn't leave change either so $98 cleaning turned into 100. They are a cash only business.
I might recommend them if you just need standard cleaning work done and no special requests as the prices were reasonable and they do have online booking.
