Very nice room (2 levels) at an excellent location if You want to stay just next to the city center. Very close to the subway and busses.
Our room was really clean and all necessary things were provided.
Dörtes and her husband were really friendly and gave us different tips to reach the city center, they also provided a small map where everything is clearly indicated.
There is also u huge parc (Grunewald) nearby for a nice walk after visiting the city center.
I can certainly advice You to book this appartment.
