from makro imelda ave, go straight lang then tatawid ka ng stop light sa junction. do not go left or right basta tawid ka ng intersection then from the intersection around 200 meters na lang ang cainta post office or municipal hall. anyway you will not go wrong kasi after the stop light may mga signs naman na papuntang post office. btw may street kang papasukan (turn right) then makikita mo na yung cainta municipal hall
