Bathrooms: I found 2 male showers and one unisex wetroom, at peak times (check-out), it was tricky to find a shower available
Access: have to get buzzed in front door, which can be tedious
Bar: drinks a little overpriced, 2.80 euros for a beer, when it was only 3 euros in Berghain and less in many of the local bars, so a little expensive I think
Beds: no privacy curtains around beds so can be difficult to sleep during daytime etc.
Power: very few places to charge phones and stuff. One socket in our room (by the door, not ideal), a few in the common room or you can leave you phone with reception, but not ideal
Lockers: no access to lockers in the rooms, only in the hallways, a bit inconvenient when showering etc.
Staff: excellent welcome, helpful and friendly
Location: In a great spot for bars and places to eat, handy for the clubs and nighlife around Kreuzberg
Social: the common room/bar area was quite a nice spot to hang out and chat with other travellers
Clean: bathrooms and beds/bedding were clean and decent quality
