Look into the tutorial you need to define the iconAnchor

How to find out, the correct anchor:

Create a default marker on latlng and one with the custom icon with the same latlng. Then you see in which direction the custom icon needs to be moved, because the default marker is centered correct on the latlng.

var defaultMarker = L.marker([0,0]).addTo(map);
var customMarker  = L.marker([0,0],{icon: L.icon({iconUrl: 'images/***.png', iconAnchor: [-3,9], popupAnchor: [0,0], tooltipAnchor: [0,0]}) }).addTo(map);
