Singer hostel is a fantastic hostel in East Berlin with good connections to the city and a really friendly and welcoming atmosphere. I stayed in the four bed dormitory and found everything to satisfaction. The bathroom was cleaned every day, the bed was very comfortable and each person had a large locker for storage of personal belongings. Staff at the front desk were extremely helpful and friendly. There is a large buffet breakfast available for 5 Euros and every other request was met promptly and efficiently. I think this is great value for money and is a fantastic base from which to explore Berlin.
