This was actually one of my favorite jobs though it was strictly transitional for me while I looked for another job. You clean, you do laundry, you fold. Very simple job, you don't need to think about it at all. At my place of employment I did everything myself so I could put my headphones on and rock out and just clean and get paid for it. It was also very interesting to see some of the aftermath of hotel rooms -- especially if they are a little shady and motel like. <3 I worked at two places -- one I worked by myself, all one floor, I had a mop -- awesome ($5/hour in 2006). At the other job, I worked with others -- I had to carry vacuums and things up and down the stairs and I was not given a mop, just a spray bottle and a rag to clean the floor. Eh. All for only a dollar more an hour.
I had about 8 months of work experience. It was okay for me. I like to do a job where I pretty much know what to expect. I was self-employed and it paid fine. If you want to do well as a self-employed housekeeping cleaner you really have to get good references and promote yourself well.
