It's a rainy day as I ride my motorbike into the East Berlin district of Treptow. Commercial areas, railway tracks, old buildings and gloomy corner pubs. My destination: a visit to Germany's first home for LGBTI refugees. As I make my way past parked lorries and building sites, I look for the home and am more than surprised when I suddenly find myself standing in front of a bright new building. After a check by the security staff, I am greeted in a friendly manner by Stephan Jäkel.
