We went to this hostel with my partner after booking it online. The particularity is that there is no reception desk but an intercom. The person in charge arrived one minute after we buzzed, gave us the parking card to park righ in front of the hotel, and gave us the key to the room. And that was the best surprise : huge bathroom, beautiful room with brand new furniture and fully equipped (fridge, corkscrew...).
Concerning the location it is great : three U-Bahn stops from the famous Alexanderplatz (so you can travel with the discount short-distance ticket), rent-a-bike for 10 euros a day, safe neighborhood. I really recommend the place for an student-budget friendly romantic stay in Berlin !
