It was a good compromise / good value if you look at price per night. Stays in Berlin are not cheap and the price here was ok. Hotel amenities were not perfect, but there is everything what you need.
Minuses: no hot water in shower, only a bit warm; the hotel equipment is old, using an elevator there is a trip to the past ;)
Pluses: price per night, not far away from the city center, good access to public transportation, friedly staff
