Located in the west precincts of Andheri, J-504 is best described as laidback. Not the quaint sort of laidback, but the rugged unkempt kind. Nestled between two impoverished settlements at the fringe of what might be called civilised society, J-504 nevertheless enjoys a magnanimous view of Gilbert Hill. What makes it cool is that, it’s the only monolith column of black basalt rock squeezed out of Earth 66 million years ago. The customs check happens on the fifth floor of a rundown building, through a door that has a portal-like opening at its centre. The locals are likely to peer at you annoyed in case of a surprise visit. Trespassers like salesmen and anyone in want of money are received with caution and are most likely to have their visa shortly rejected.
