If the place looks like a bomb hit it, I will probably not book with her again. I try to book a session as early as possible so the room is clean and there are plenty of towels.

Whether it is her regular incall or a hotel room it sets the expectations and usually the outcome.

they also matter when trying not to raise eyebrows. I would go farther to say it also falls into the category of personal representation, discretion and consideration for self and others. All of those things matter as well as awareness of what is going on around you at all times all the while not watching a clock at all...for some that requires finesse - for me it comes quite naturally.
 Personally, I enjoy quiet music - perhaps chamber music or smooth jazz and a dimly lit atmosphere complete with mini candles, sumptuous lingerie and a relaxing time for two...
