Karen was excellent with communication. The apartment was easy to find and very well located, just a few blocks from the "Kapelle der Versöhnung," (on the old east/west border) and a subway station. It was well-equipped, clean, and functional. Walking in the evenings along the nearby memorials / information sites / parks associated with the wall was very pleasant. The center of the city was also reachable by foot in about 30 minutes. Some meter-readers did knock on our window at around 9:30 in the morning on our last day (before we were fully clothed) to gain entrance, which was a bit surprising.
