I certainly can not pass without specifying that, each employee is quite sincere, friendly, loves to help. Yes, there are certain shortcomings. But what is important here is that the price balance element combines quality service with backpackers. By the way, it's a hostel not only for backpackers but for everyone. You pay quite a small amount for breakfast and voila! The same goes for happy hours.
It is quite centrally located. Many places within walking distance. No, if you say I don't enjoy walking, you can easily reach the most important places by train, metro and buses.
I stayed in a mixed room for six (Ladies please could you be much clean then men ?!). Bathroom and toilet in the same room but separate. I think that's good. It was a very quiet room. Hot water and room temperature - which Berlin was cold at the moment - were adequate.
Thank you guys.
