Location, location, location. Right in the centre of Berlin with loads of restaurants and nightlife and walking distance to Museum Island and Unter den Linden. Public transport very close by and a direct S-Bahn to the airport only steps away. Despite being in the centre, the apartment is on the side of the building away from trains so it is relatively quiet. The apartment is small but big enough for a couple. Highly recommended for a city stay. Very good value.
