It has nothing to do with the announcement. It is 1,7 km walking to postdamer platz, it’s a underground flat with an entrance (with downstairs) direct from the street that people used as toilet. One of the rooms has the windows direct to the street with the covers broken, where you could hear every word from the street, cars driving just over your head and with the train even feel it in your bed trembling every 5 minutes. The rest of the house is ok, beds are ok, but that room was really really noisy.
