Rainer answers very quickly to your questions and is very hospital. He let me to left my baggage after my checkout. Rainer is a very kind and hospital person. The place is 400m away from underground station. There are several small cafes and shops nearby. Also approximately 700m apart there is a big supermarket which opens till midnight. The appartment is very stylish and pretty comfortable to stay. Also there was a sound system with Bluetooth aux functionality which I enjoyed a lot!
