The location of the hotel is not a typical holiday location: In the backyard, you find the tram station, in the front the Tegel jail (JVA Tegel).
The hotel itself could definitely use an update, but don't let yourself bother by this description: The personal is friendly, the parking is for free (but limited; anyway, in Berlin use the public transport and not your car!), the jail itself is also worth a look. Behind it, there is a park; on the Bernauer Straße you will find a supermarket with good quality food.
The price for the rooms is ok for Berlin. I had some allergy problems probably because there were feathers in the pillow. The room itself is very clean, the bathroom, too.
The flushing did not work (room 228), but I will inform the manager.
Very convenient: The tram station is behind the hotel; you have to walk only some seconds from hotel lobby to the station; you have really good connections to the town.
In my room, working was not really easy as it is really small. WiFi is free.
