The location of the flat will be convenient for many people who can comfortably walk at least 750m to reach the closest Ubahn/Sbahn station or vice versa. There are bus stops, almost 200m away from the flat. But, to reach main touristic attractions, at least one transfer from bus to metro station, or 750m walk needs to be done before the metro. This may not be convenient for people with babies or disabilities. It may not be a good idea to rely on the bus schedule, as it may not be as frequent as metro alternatives. Also notice that after midnight, transportation alternatives are limited and less frequent. If you are not planning to stay long enough to understand the Berlin transportation system, you should evaluate other alternatives closer to main transportation hubs. BVG application is very helpful to decide which transportation alternatives and combinations one can use depending on the current location to reach point of interest location.
