Great place in the middle of everything. S-bahn is about a 8 minute walk away and connects you to everything. Loads of good restaurants all around the place. 4 flights of stairs in a clean building. Felt very secure at all times. Uwe was very prompt in responding to issues and his man Marcel showed up and took care of things when needed. I highly recommend the place to anyone looking for a no-frills accommodation to visit Berlin.
