Hotel is located in Charlottenburg, with free street parking. In the area there are plenty of restaurants, while the Kurfuerstendamm and Wilmersdorf are at short walking distance. Plenty of public transport nearly into Berlin center or the Tegel airport.
Room was convenient, with airco, and clean. Good size, decent bed and clean bathroom. Wifi free and ok.
Breakfast fine, but perhaps below par for a 4 star hotel. Service good.
Nothing wrong at all with this hotel, but 4 star may be a stretch, and with breakfast there may be better options. But I had a pleasant stay and would consider returning.
