We (3 persons) stayed in the apartment for 5 nights for a business trip. We were welcomed by Thomas' daughter who explained us how everything worked, and there were also some more written instructions. The apartment looked exactly like the pictures, and we felt very much at home. The living and kitchen are very spacious and comfortable, and also the bedrooms are huge (especially the two upstairs). For us it was also very convenient that there were two desks to work on in one of the bedrooms. The neighborhood is also great. Many great restaurants and shops nearby, and a big grocery store at the corner of the street. And if you would like to visit some other places, public transportation is very nearby. So all in all it is a very nice apartment which is located great and we would definitely come back when we visit Berlin again (either for a business trip, or for a private trip).
