From the Riverside, walk to the Old Market and up that street. Turn right at the Acleida Bank, then walk until you reach Lucky Mart and the Salt Workers Roundabout. You'll want the second street on the left (with Light Star Hotel on the corner). We're the third building on the left. Easier than that, you can hop in a tuk tuk and ask him to take you to Monkey Republic - we are well knows amongst tuk-tuk drivers.
