Great location! It was my first time in Berlin since I was teenager. Now I went with my two kids. The location is superb. Close to communications, supermarkets (although all are closed on Sundays) bars, restaurants and cafés.
The room is well equipped with what you need for a short stay when it comes to cooking. It's nice and clean, and there's an heating stove (which we didn't need at all, but that I guess can be very nice in the autumn/winter). Outside you have a table and benches where you might have your breakfast/meals in a very cozy enviroment.
The only thing that I could complain about (which is not really a complaint, more like a personal preference) is that there's no smoking allowed, not even in the garden. But if one really wants to smoke you can go out in the street, which I did.
All in all, if you're visiting Berlin, this is a great place to stay!
