Five star service the entire time, especially from the reception staff. It was the thing that stood out for us.
The breakfast buffet was fantastic, and eggs cooked to your liking on top of the large variety of options.
The location is just off Salinger tor, a major tram and subway hub. It is also just outside the walls of the old town. We easily walked everywhere.
Our room was quite large with a king size bed and spotlessly clean. Without a doubt I will stay here the next time I'm in Germany.
