This place was bang-OK. The problems were many. The single room is tiny (tiiiiiiny), with an ageing shower that vacillated between hot and cold with German efficiency, no air con in a heatwave, situated in an area of Hannover that was extremely noisy through the night (with the windows open as there was no A/C), the walls between the single cells, I mean rooms, are so thin my neighbour's gentle snoring was audible, and his choice of TV station discernible at 6.30am, and almost as annoying was a key card lock that failed every day – literally every day. When you're on the third or fourth floor going up and down to try a key each day (one day it failed 4 times) this is a major pain. I'll score this place generously but it was not a highlight of my trip to Germany and I'd avoid this hotel at all costs if you're even tempted to stay in the cell for one.
