It was my first trip to Berlin and my first stay at a hostel, and the Sunflower Hostel was just great ! A big building close to the metro station and to buses and trams, the friedrichshain neighbourhood is very young/hipstery/vegan friendly, with a lot to do at night in the surroundings of the hostel ! The staff of the hostel is very nice and the bar downstairs with the shared area is perfect to make some new friends, the place is clean, bathrooms are big and functionnal. Nothing bad to say, really !
