The apartment is more like an office with the bed. But it doesn’t mean it is a bad thing. It is really stylish, the kitchen is equipped, bed is big and comfortable. Check in/out process is easy. So if you are coming at night (as I did) it wouldn’t be a problem. The location is perfect, just 5mins to Bahnhof, about 15 with Sbahn to city center. Sebastian provided a lot of helpful links and discounts codes that can help you if you are staying in Berlin for the first time.
