Just for fun, take a tour through the recent reviews:
Not all reviews mention the soap and towel issue, (I suppose some people don’t wash their hands after using the toilet… and some may not need more than two towels), but the ones that do give a pretty clear picture that the hotel simply isn’t giving these things out, even on request. In my case, I had to press pretty hard to get a little tube of shampoo from housekeeping to put by my sink. (I briefly considered offering to shake her hand…)
