Hi, its for sure Tempelhof (EDDI), Tegel is for airlines only, or mostly..., Schönefeld (EDDB) is in the south and has no night flying restrictions (Tempelhof closes at 10pm loc, Tegel I guess 11pm loc). If you go to Tempelhof (what I highly recommend) use TAG as handling.
Otherwise all easy going. If you land on 27 look right on short final...
Have fun and enjoy Berlin!
