Yes, it needs to be the same over at least three days. At 1.011, it's probably done but not necessarily. If it drops to, say, 1.009, in the bottle it can lead to overcarbonation so you don't want to consider bottling until it's stable.
That said, after three weeks I'm surprised it dropped .004 points in three days. It should have been done a long time ago. Normally, FG is reached in 5-7 days at the most. In any case, wait two more days and then check it again. If it's at 1.011, and it's clearing up, then it's fine to bottle.
