Generally softer water is nicer. Get a filtering jug and pour water from that into the kettle. The nicest tap-water in Britian is Welsh; because of the mountains the water is softer, therefore, nicer and makes amazing tea.
Milk, sugar, honey, sometimes icing it makes it better too. You can add your milk and sugar then add ice that's how I like to drink mine anyways.
put honey, evaporated milk and sugar in the raw in it :]
