Stayed here for five nights during the summer with a friend. Felt very safe for two girls in their young 20s. Stayed in a six person room of just females. It was noisy sometimes and a little messy, but that should be expected if you're young and sharing hostel rooms. Lots of young travelers but also saw familiies using the hostel. Clean bedding and bathroom. Great staff with lots of knowledge of the area. It was in a good location, very close to both U-bahn and S-bahn. Rooftop bar for guests only, really fun and great bartenders with cheap drinks.
