This hostel doesn't have a lift so if you are gonna carry a luggage, you wouldn't want it to be heavy but it is still fine to me even though I was carrying a pretty heavy luggage. The staffs can speak English very well but sometimes the attitude was a little bit not friendly. The wifi works until you use your own Facebook account to log in but it is a little bit slow. The heater in the room is warm enough and the floor is clean. The bed is comfortable and there is plenty of space for putting things. There are electrical plugs located near most beds so there should be no problems of charging while sitting on your own beds. The showers and the washroom are clean.
I love the idea of having sensor lights and lamps but sometimes you need to stand in a specific place to keep them on and it was pretty annoying. The kitchen was messy and almost everything was pretty dirty so I didn't use it. There are some nice and cheap restaurants in that area too!
The location of the hostel is pretty convenient but the entrance is a little bit hard to find. It is near the Check Point Charlie and railway station so it is really convenient to explore Berlin.
