This is a beautiful apartment about a 10-minute walk south of the KaDeWe. Its high ceilings and large windows made it a pleasant place to spend time. It is non-smoking, quiet, and clean.
It is within walking distance of several public transit stops, making it convenient to get around. The immediate neighborhood doesn't have much of interest, however.
The apartment was missing some basics: there weren't clean dry towels for both of us to use upon arrival, and the tiny host-provided pillows are more appropriate for an airplane than a real bed. The bathroom door doesn't close properly. The check-in procedure wasn't great--make sure you are clear how to get in touch with the contact person before arriving. The host was nine time zones away and non-responsive when we arrived.
The decor and art was very nice. All in all, it was a great apartment that we'd be happy to revisit. With a few minor fixes, this place is a clear five-star apartment.
