Unfortunately, it is very hard to find a place to stay at the moment, and most places offering shelter for refugees are already full. However, there are a few places you can try to contact:
1) The Salvation Army is a Christian organization that is LGBTI-friendly.

2) The LOS foundation helps undocumented migrants and their children.
They also provide a helpful list of organizations for emergency shelter:
