The location of the hotel is quite convenient, close to the Ubahn (subway) and not very far from the busy historic town center (one subway stop, or 10 minutes walk). I stayed in a single room (with a small single bed), which wasn't very big but had all necessary furnitures (large closet, desk, minibar...). The bathroom was fine. Everything was spotlessly clean.
Most (if not all) rooms have a window overlooking the street, which gets quite busy in the morning (rather quiet at night). The noise was contained to a very acceptable level in the room (double window, quite efficient) but is quite loud in the breakfast room when the windows are open (ie when the weather is warm).
The staff is efficient and friendly. Free wifi service is available in the room (just ask for the password at the reception). There is a hotel bar but I didn't get the chance to check it.
All in all, an hotel OK for a business stay but maybe not suited for a long, touristic stay because the small size... more
