Arnd was very friendly and hospitable. We barely saw him at at during our stay. The room was very comfy and cozy. The bathroom was very clean and a big bathtub! It's very close to the hbf station/transport. Not very close to delicious restaurants but we loved walking around to find places. There is an Indonesian restaurant called Nusantara that you can walk to and the Neumanns restaurant to the right of his building has a delicious apple strudel and vanilla ice cream for a late night treat.
