The flat is very quiet though in the centre of Berlin Mitte. It has just been renovated inside and perfect to enjoy and get the Berlin feeling. 7 minutes footwalk to Hackescher Markt such as 2 minutes to Rosenthaler Platz. Plenty of bars and also supermarkets around.
I would expect you to behave the same way you behave at your house. All neighbors are very friendly open and respectful.
