Sunflower Hostel in Berlin Friedrichshain - room in the front part of the house in the 2nd floor - view outside the windows to the Mecedes Benz Arena and Metro at night

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.
