After over an hour in the cab, I finally arrived at this dingy hostel.  Señor Taxi Driver charged me up the butt, and after a pathetic attempt to negotiate I paid the full amount.  He had my bag in the back of his car; not much I could really do.  First Peru lesson: always negotiate the price BEFORE you step into the cab.  I shortly thereafter learned my second Peru lessons: the clunky showerheads in cheap hostels will electrocute your head if you brush against them.  Good times.
