There really is no better place to stay when you want to be connected to the whole city. Directly next to a station and 3 stops on the U2 to access Alexanderplatz, it was so easy to stay here and hit every spot we wanted to see. The bed was so comfortable and the kitchen had an oven and a stove top. Very convenient for cooking as there is a ReWe not 3 minutes by walking. I would say there is room for two adults and child no older than a preteen if you want to be comfortable. Over all I HIGHLY recommend staying here for your time in Berlin.
