I love Tempelhof.
Over the past two years I have flown into and out of it a few times in a Piper Cub with Flugholm and it is a an amazing place.
The walk in from the subway station is a sight to behold. The architecture is stunning and the atmosphere inside is still one of old style travel albeit much quieter now than before.
If you have no been there and have some time to spare, I would highly recommend a visit as if this place goes, you will not find another example like it on this side of the world.
