It’s a nice hostel and you can sleep way better than in a normal one due to the privacy. Just get some earplugs. I only slept there two nights and the first night not at all because two girls left at 3am and made so much noise. Also it’s very awakening when someone opens his curtain. Also you could get a room next to the train tracks like me which is really loud. The bar downstairs has some good food and a small selection of drinks. I can recommend hanging out there in the evening when there’s maybe also not a big group of Germans playing loudly cards...
The staff is friendly in general and helpful.
