We found the location very convenient for travelling around the area. Two minutes from the nearest U-Bahn, Spttlemarkt and only a few stops from Alexanderplatz.
This gallery/apartment is quite unusual with a large display board in the main front window which blocks the street view but also, unfortunately, most of the daylight. One bedroom also had sliding display boards in place of a wall and door. I was not a great fan of this arrangement but it didn't spoil our stay at all.
It was also a great help that we could leave our luggage during the day as we had an evening flight home.
