I had the most fantastic experience at Bernd & Katja's. Their place is simply perfect. It was extremely warm and peaceful. Situation perfect for travelling (either Tegel or Schoenefeld). Close to nice eateries (my favourite was Zeit fuer Brot). Brilliant hosts, quick to respond and couldn't be friendlier or more helpful. Really just the kind of place where you feel nostalgic even before you have left. Would come back in a heartbeat! Many thanks Bernd & Katja.
