From the Highway you take the Altamira Distributor and go North towards the Avila.  After Av. Francisco De Miranda, get into the left lane; you will be passing Altamira Square.  Take a left  at the 3rd Transversal; a one-way street going left.  You will cross Av. San Juan Bosco and then see a church complex on the left... with a white wall and triangular clock tower.  Take the next left into a Calle Ciega (4th Avenida) and look for hashers mulling around.
