Coming into Isabel II from the west on PR-200, go past PR-997 (the road to Esperanza) and past the new gas station. Immediately take a right on the Mambiche Bridge. At the first Y intersection, go uphill & to the right for about 250 feet. At the next intersection, go left (at 90 degrees). Do not make a sharp left or a sharp right. Turn right at the very next corner. The house is the third one on the left.
