Perfect central yet quiet location to explore Berlin from, you're right next to the KaDeWe, Ku'damm, Zoo etc. Ceasar couldn't have been more helpful, communication was clear and quick. You get a nice clean single room with window to the street, I had the window open overnight and didn't have any problem with noise. There are shutters on the outside which makes it secure and you can get the room completely dark if you want. There is a massive bath, water temperature and pressure excellent 🙂 Would definitely recommend.
