Nice modern furniture, super clean, friendly staff, good location, and excellent breakfast.
But several misses make the stay uncomfortable. First, You must know German to understand any of the instructions - not a single word in English (or any other language); obviously they are not catering to foreign travelers. Second, rooms do not have refrigerators. Third, connecting to the Internet is a complicated process that requires help from the desk, and the speed is quite pathetic. Fourth (and most bizarre) there are no electrical outlets near the beds or the desk. So you must charge your devices on the floor near the bathroom door!
