Awful.  They look clean and competent - but every time I go there (and this is my last) - the car seems actually dirtier than when I arrived!  How is this possible?  Well, after they hand it back to me, there are crumbs etc on the seats (sloppy vacuuming) the  cupholders and console still has stains - I  mean OBVIOUS stuff.  There wasn't a visit where I had too send them back 2-3 times to re-vacuume  or re-wipe the inside.  I am no clean freak by any means,  This was just sloppy work,  Consistently.
