The "Sunflower Hostel" in Berlin is one of the best hostels in Berlin. It is rather cheap and has a 24/7 check-in with rooms with or without a bath room (LGBTIQ-friendly; insults or attacks against any minority will not be tolerated). Its service at the reception (= the bar from 22. p.m. to 5 a.m.) is great. There are literally people from all over the world (English as the traffic language). You should always check for free beds the homepage directly. I enjoyed my stay for about three weeks in November 2017.
