The hotel is in very convenient location, which is within a couple of minutes to the closest train station. It is also within walking dustance to mwjor landmarks, such as the Brandenburg Gate, Museum of the Murdered Jews, and Checkpoint Charlie.
However, the hotel has awkward hours, such as unavailability of the gym, sauna, laundry, and ironing board during non business hours. The breakfast is repetitive, but the wait staff are super friendly.
Overall, I would recommend the hotel if the management decides to extend gym and laundry services during non-office hours.
