The apartment was nice and Kathrin was very responsive. The house rules about late checkin was interesting. The later I checked in the higher the fee, climbing to 200€ due to arriving at 0630 the first night of the reservation. The apartment was just what we needed with a nice view of the Berlin TV Tower. Since the apartment was equipped with a refrigerator and stove and we drove to Berlin we brought food to cook. The refrigerator light stopped working but we later realized the entire refrigerator stopped working causing our food to spoil. I changed outlets but it still remained inoperative. Kathrin felt it was too late to switch out the refrigerator and rejected my kind request for her to provide some kind of compensation for the spoiled food due to the malfunction of her refrigerator. Other than that we had no issues with the stay or the apartment. Nice view with parks and grocery stories very close by. In fact there was one right next to the apartment building. Good location and nice view.
