Stayed here for my final light in this shared room hostel and in retrospect would have found it comfortable for a longer period. Excellent purpose built building and facilities, 24 hour reception, comfortable lounge and seating. Fast wifi, bedroom as clean and warm as was the bathroom. Friendly and efficient staff and all you can eat breakfast for 5 Euro. Nearest train station was about 15 minutes walk away, with a journey of less than 10 minutes into the centre. If you are in Berlin on a tight budget (or even not), this place comes highly recommended for great value.
