well structured place and clean desk gives writer good sense of control for her writing. First essential thing for writer is good environment and quite place so author can take her realm of imagination at its best and give word to the story what millions can relate too.
As writer i do not have fixed time and place for writing. As a writer you get inspired by many things when you do your daily activities.. Once you feel happy and content about everything you start micro scoping everything and good writing takes it own shape.
