This is a very basic hotel, occupying just one floor (4th floor with lift) of a large old Berlin mansion block, but it ticked all the crucial boxes for me, so I was happy - decent value, clean, central (less than five minutes walk from Ku'damm and Adenauerplatz metro station) and my deal came with FREE internet, which was not the case with many of the more expensive hotels. Breakfast was quite simple, e.g. no fresh fruit, but the rolls were perfectly fresh and the breakfast was fine. The owner has the world-weary manner of a prison governor and he didn't waste any energy charming his guests, but the room sells itself on it's other merits, so maybe he doesn't need to try too hard. I liked this hotel and would very happily stay there again. I do think the hotel should invest in better sound proofing between the rooms, but since my neighbours were very quiet, it was not a problem for me.
