We are a famlily of four and had a very nice stay. The location is perfect. Close to everything you need. Bakeries just outside on the street, 300m to supermarket, and a short walk to Kurfürstendam. Busses near by.
The room we had was spacius, with a small kitchen. It had all the basics you might need. We bought our own breakfast at the bakeries, but the hotel offers a breakfast buffet as well. Did not try it, but it looked nice.
Only thing to note is that the sofabed is not really suitable for adults, only children would be able to sleep well in it.
