I assume you are referring to Leipzig, (EDDP).
I have been many times in past and it is quite a nice airport to fly into. The controllers are good and they have 2 large runways, all of which are cat 3 ILS I believe.
It is usually not very busy during the day, but is quickly becoming one of the largest cargo hubs and really comes alive at night. The southern runway is usually utilized by cargo aircraft. During the night you may expect to do the full rnav Sid/ star.
I unfortunately don't have any info about the airport handler or general aviation terminal.
Downtown Leipzig is quite nice and I'm sure you will enjoy.
