Daniel is a charming host and made our stay as pleasant as possble. The room surely is unique, as it's also a part-time Gallery. The furnitures are authentic and the room is quite big and generous. For a stay of a couple of days it's perfect, the location is calm on one hand and on the other hand very near to some very cool locations (Boxhagener Platz, Simon-Dach-Str., etc.).
I would recommend the Room to all my friends that want to stay in Berlin for a couple of days, since everything was great.
