This hotel was exactly what we needed for a 3 days visit to Berlin. The location was central. Noise levels low and the staff friendly and helpful. Breakfast was basic but good. The rooms where nice and big compared to some other similar star rated hotels. Wi Fi, although not free, worked without any hassle. There is a small kitchen in your apartment/room and with several convenience stores within 5 minutes walking from the hotel it makes the Heinrich Heine a good choice for self-catering.
