The staff were ok. The location is great, it is close to the zoo, Biertheimer Allee which is a very nice little park.
We made a reservation during the summer, our room had a very small AC, which was not even make the room just 2 or 3 degrees cooler. Very hot, difficult to fall sleep. The minibar was not working, even the water bottle they put in the minibar was hot! Breakfast was very good but still in a warm room, where also flies were flying around.
Other than that everything was fine!
