I would suggest two hoses. A rubber hose such as the others have mentioned and a coiled hose (the cheap yellow kind is fine). The rubber hose is great for things like impact wrenches that need a shot of air. However, for filling tires I've just found the cheap yellow hoses are easier to deal with. I don't have to coil it back up before putting it away, just hang it on the wall. Thus I have both.
