It will be ready to be bottled when the gravity stop dropping, Altough you are getting very close to the bottom of it. Just take another reading in a day or so and then it is still 1013 go ahead and bottle.
Having said that that beer will improve in quality the longer you wait. I usually wait 5 weeks for that one before bottling it. I know how hard it is too wait when you doing your first beer.
How did it taste by the way?
