This is a great apartment, perhaps especially for a family traveling with 2-3 kids. For me, as a single traveler it was more than I needed! The elevator was a learning experience and a literal "lost in the translation" problem, but once we got that figured out, everything was great. The location is super close to Alexanderplatz, Museum Island, the Cathedral, Staatsoper under den Linden. Those are all easy walking distance (<1km).
