You definitely get what you pay for. We got a bottom bunk for two of us and it was definitely enough space to sleep, but not enough space to feel downright comfortable during the stay. Place is clean, has enough space for your bags, bathroom is clean, floors are clean. Being a hostel, being quiet for your surrounding neighbors are a must.
If considering this place, I would recommend getting the private room. It has more space and gives you the luxury to move at your own pace.
Overall great first hostel experience. Host was quick to respond, always friendly, always answering my questions in a timely manner. 10min walk to the closest station. Pretty Central to a lot of places.
