My cider went from 1.050 (no added sugar) to 1.020ish in three days. It was pretty clear then, but after two weeks it's brilliantly clear. It's been at about 1.004 since day 5 and I'm in no real hurry to bottle it, but I could if I wanted to.
Just remember that if the cider isn't yet clear, when it does clear all of the sediment will fall into the bottle if it's bottled early. That's really the only drawback to bottling early if the hydrometer readings are stable.
