Stefan wasn't available to welcome us but somebody was there, and the appartment was ready when we arrived.
The appartment is exactly like on the pictures, very clean and nice. It is not a real 2 bedrooms as one of the double bed is in the dining room but still very comfortable.
The place is very convenient, opposite to the Ubahn. A little bit noisy for the rooms on the main street but very quiet on the other side.
I would recommend this appartment.
