Because of my flight, it was around midnight when I checked in, but the process was smooth and the person at reception was thoughtful enought to give me an empty room! There were 2 sinks with mirrors and outlets in a 5-6 person room, and the lockers big enough to fit in my carrier. It's a large, slightly old-fashioned hostel, meaning you have to cover your own sheets, but no biggy. No personal oulet next to the beds but plenty in the room, public showers and toilets were spacious and warm, food was good. A lot of guests were families or students on school trips. Overall, I had a great stay, and definitely will come back if I return to Berlin on a budget:)
