Jo's Place is located just 1 street off the central Avenue Centenario, which runs along the western side of the Plaza de Armas (which is the side opposite the cathedral). From here, walk 8 blocks until you hit Jr. Villaizan, turn right and the hostal is one and a half blocks up on your right. (Tip: Look for the bright blue wall). From the multiple bus stations around Huaraz, a taxi should cost no more than S/3.
