The 24h reception is super convenient, and people sharing the rooms are usually nice. I would only have the bathrooms in the rooms be a bit cleaner (remember to bring flipflops), but other than that we had a very nice stay. It is super connected to U-Bahn and is basically next to Alexanderplatz. Great choice for backpackers and the best choice in terms of quality-price relation!! 10/10 would recommend.
