I found them through Craigslist. I did the 2 maids for 68 dollars for two hours. First thing was they were pretty late, about 30 minutes late. But I am understanding as I do live in a far flung area of the valley.
They do speak very little English and I speak a little Spanish but we were able to communicate well enough. For the amount they charge, I was pretty satisfied. I only needed a basic cleaning, but I would not hire them for anything more complicated due to the language barrier. I will consider using them in the future because I like that I can book online.
update: I tried to use them again, but they are a no show. Very unprofessional. They lost my business.
